Font changes from Open Sans to Helvetica while typing the letter L

[Eirik25986101bvfp]

I am currently working on an AE comp (v. 23.1.o Build 83 - Mac OS Monterey v 12.6). I created a new comp and some text layers and discovered when typing the word "PEOPLE", the letter L automatically shows up as lower case and when I try to type it UPPER case it changes the font to Helvetica. It only happens when using the Extra Bold font style.

Thank you for reporting this - it is intensely interesting to me because of recent work that I have been doing with fonts.

So far I have seen this internally somewhat randomly with OpenTypeVariable fonts exercised via scripting but it seems hard to image why that might be the only trigger.

Can you tell me what font (okay Open Sans) and font version and where you got it where you are seeing this?

Are you using faux (bold/italics/etc) settings?

Are you using small caps setting?

Anything else out of the ordinary to note? Any success in getting to go away? Fonts where it never happens? Only capitals?

Hi! I have the same problem on Windows. The difference here is that "P" changes automatically from Open Sans Regular to Myriad Pro

I'm having the same problem but with the letter A and the font Unbounded in regular, it changes to Helvetica regular by itself

I'm also having the same issue, the capital U automatically changes from Dharma Gothic E to Times New Roman.

For what its worth, I found a 'solution' by typing the text into a different composition and copying the text to the original spot.

Same issue here, just with the letter "O", changes to Times New Roman and won't be corrected. Everything is updated.
The font I want to use is Blender Pro which works fine in every other Adobe App. It only occours with the style "Heavy".

has this been since figured out? Im trying to write text in Oswald, but the lowercase r's jump to times new roman with no way of changing them back

Also still noticing this on every 16th character typed locking into Helvetica and not allowing the font to change

This just happened to me while using a custom font--the solution was to restart AE.

I can confirm. I have the same problem. Font that was installed in my system changes to Times New Roman mid typing or a single letter or number will be in that font.

I also am having this issue with capital S in Montserrat changing to Helvetica?

same problem, pls fix it, it's annoying

@JohnColombo  I guess at this point there is enough info to regognize this as a problem with some manually added fonts.

My problem is related to "Mona Sans" that was downloaded from Google Fonts.

No faux settings.

Normal text, Cappital or lower letters, mostly - t , n , m and numbers and more often when the weight is selected to "Light". 

If I manually select the broken letter and I set it to Mona Sans it works. If I change the font and go back to Mona Sans I have to manually fix the broken characters again.
