Expressions link to effect name does not update correctly in AE24 (and beta25)

[vobrazovka]

I have motion graphics project, where we shows prices of products and price numbers are linked by expressions to controller.
In after effects 2023 everythink works well, but I can not switch to new versions, because then displayed prices are mixed and flickering between different numbers every few frames.. 
It is obvious that this is bug in AE24 / 25. 
When I resave it from AE23 as xml or AE23 project and open it in AE23, it starts working well again. 
I can share project for further investigation, if someone want to observe..

It seems to me that we already addressed this topic at the beginning of the year,

we worked around the issue by converting the expressions into keyframes or using a script to edit the text values and disable the expressions.

[vobrazovka]

It is not possible to convert to keyframes.. It is "template" promo video project (not mograph template) for one discount shop. It is used every week. Just changing products and price tags.. It must be maximal effective, due to low budget and unvisal. Of course, I can edit text directly in pricetags.. but it cost additional time and no one will pay for it. So we still sticks in AE23 with this kind of projects (it is about six different projects with the same issue) and for other stuff using AE24

I found the topic, we used a script to fix the issue.

But yes, share the project for further investigation,

[jenkmeister]

Yes, please share the project and we'll have the dev team take a look at it.

Here is reduced  affected project..
It is working flawlessly on AE 2023. You can save it as 23 project or xml and test it - it will work..
After open it in 24 or 25 it starts flashing and altering two values of price (from different controllers). But! Not ussualy in composition where text layer is placed. The issue is most of the time visible only in main comp or one level down.. 
It is somehow sometimes works well, when I change random value of random layer (text layers anchor point, position of null object.. anything..), but it is not reliable, every change in any layer can broke it again..
We need to keep in mind which projects can be edited in 23 and which need to be opened in 24, so little bit schizo.. 😄 😄
Example is also attached.

So, first I have to appologize for missing files in shared project. There are two pngs linked, which are not necessary for example.. So it can be just deleted
And second, today I instaled first official 2025 release and it seems to be OK so far, so I will test it and if the issue persist, Ill write again. Thank you

@vobrazovka Thank you for the project file. I work with @jenkmeister on the After Effects team.

I'm also not able to reproduce the issue in the latest 25.0 version, but I'm curious which specific 2024 version you were using when you experienced the issue? You can view the specific version by going to Help > About After Effects.

Thanks again,

It seems to be a cache problem.

I was able to reproduce the bug on AE 2024 and Beta.

Just need to edit the slider name and move the CTI.

[vobrazovka]

So, after a while the same issue is presented also in 2025 😞
in studio we have to stick to 23 so far..

[vobrazovka]

Yes. It is working on principle the Text Source is linked to name of slider. so after you rename the slider, it will change in price tag..
It is working in 2023 and older like a charm, but from 2024 not

Hi @vobrazovka,

Thanks to @Airweb_AE's comment, we are able to reproduce the issue you've described. It appears this issue first started occurring in After Effects 24.5, so rolling back to version 24.4 should allow you to avoid it while we investigate a fix.

Thanks again for reporting this issue,

Hi @vobrazovka,

A fix for this issue is now available in the latest public Beta builds of After Effects 25.2. When you can, please install the latest Beta build and let us know if you continue to see the update issue in your projects.

Thanks again for reporting this issue,

Hi @JohnColombo 
It works flawlesly! Tested on couple of projects without any issue. Thank you for the fix! Can't wait for stable release!
BTW speed and response of new GUI in beta is amazing.. it looks much more fluid than the (windows) system GUI animations (it seems to me like Microsoft windows animations running on half of monitor frequency). 
So, I am looking forward for official release!
