There is a long-standing bug with the faux-style ALL-CAPS (TT) option in Font Properties for text layers. This bug affects both Premiere Pro graphic Text Layers and text inside MOGRTs.
When user applies ALL-CAPS, the text randomly displays upper/lowercase characters instead of all-caps characters.
The fix is to manually type the capital characters (a -> A) instead of using the all-caps button.
Sometimes, these also work as a temp fix for the bug:
Uninstall/reinstall font
Manually clear all Media Cache files
Restart Premiere Pro
This bug disproportionately affects plugins that use MOGRTs for text templates (such as Mr Horse Animation Composer, Captioneer, etc)

We've filed a separate bug for this. Thanks for reporting. Can you try disabling the Multi-Frame Rendering (After Effects Preferences > Memory & Performance) and exporting?
We also tried the same on our team. We still had a similar error rate, so disabling multi-frame doesn't do much for us. We did adjust the CPU preformance, number of cores, etc to tinker with various configurations. We also tried ending all Creative Cloud processes, and de-activating Adobe Fonts altogther. We added a delay before rendering, and tried to uninstall Creative Cloud completely. All of these tests had a similar error rate of around 3% to 6%, with the lowest error rate coming from a PC with a single quad-core processor (versus our usual 2 quad-core processors). This gave us an error rate of around 1%, which is still not acceptable for our use case.

Hello, this is exactly the bug that affects some of our templates. The templates affected are all completely different, and despite numerous investigations we have not yet been able to find any commonality that would allow us to locate the occurrence in the template. The bug appears only on windows platform, not on mac.It might be visible in the Premiere Pro sequence, but it can also only appear after rendering with Media Encoder. The same applies when rendering in After Effects. The problem has existed for aroud 1 1/2 years and we reported it to Adobe from the beginning. Trying to solve the problem ourselves by reworking the affected templates in various ways has not been successful. Every possible approach has ended with the error reoccurring again. We test from version to version, but the problem has not been resolved as of the 25.2 beta.
We are aware of this issue and have a ticket open to investigate a fix.
As a workaround, you may want to try disabling Multi-Frame Rendering (After Effects Preferences > Memory & Performance) and re-export your mogrts to see if the issue clears up for you.
Any movement this? I've attached an image of another example: (Font is Rubik Medium installed via Creative Cloud, running the current version of AE). Closing this and re-openning seems to fix it sometimes, other times not. However, with our use case, we don't have that luxury, as we run thousands of automated renders daily and can't check each one manually. Thanks!

I'm also facing this issue for about a year now and never found a permanent solution to this problem. clearing media cache works often but not a permanent solution as if my project crash or I manually reopen that project, most of the fonts will again go crazy like random letters are small and random are capital. I reinstalled my software many times, this is not just happening with Mister Horse text, mostly with their mogrt files but also with premiere pro default text graphic. Please fix this bug as this is very irritating, can't checkout full video each time I export for clients. mostly exported videos have those random capital letters so I have to clear cache or sometimes change fonts completely to fix them and render again.
I've already avoided setFont for testing purposes. So, some of the problem layers in my example contain setFont expressions, while others don't. There's no difference regarding the bug.

It's already like this: One of the MOGRTs no longer contains setFont, but it is still affected. Do you think it's possible for a single mogrt (with setFont) within a Premiere Pro sequence to 'infect' another mogrt (without setFont) within the same sequence with the bug?
have you found a fix for this now? also done clearing media cache it works from time to time but sometimes it don't the only solution i do is manually using capslock it really is time consuming since i do long videos with a script, i usually just copy paste the script to my project to make my work more effiecent typing them takes time.
I'm sorry to hear about this. Is this happening with any specific font or with all of them? Did Peru Bob's suggestion of reinstalling the font help resolve this issue?
I can't use another font as this is the brand related font, and I didn't try reinstalling - I just retyped all caps in the boxes instead of trusting adobe to apply the all caps setting and that workaround worked for me.
So, yes, I gave it a try and everying work as expected:
There's just an .AEP in the files so I created the mogrt from AE, (it gave a warning of a non-adobe font), I continueds and dropped it on a timeline in PP (beta 25.4. b72) and it works fine. I then opened that project in 25.3 and it still looked good and worked fine.
