Dynamic link edited text linking to duplicated asset text

Hi there!

I am working in a team using a linked AE comp for a lower third. This is used on various iMacs and an Apple M1 Max Studio in Premiere 24.6.1 and After Effects 24.6.2.

This AE comp is duplicated with different part numbers written in (Part 1 of 4, etc.), and used in multiple sequences. Recently we've enountered a bug where one instance of this AE comp is linking to a duplicate of the same comp, where the part number will flicker from one number to another during playback.

So in a sequence where the lower third is supposed to say "Part 1 of 4", the "1" is flickering to "2" in different frames, which will be typed in a duplicate of the same AE comp. Sometimes playback will look correct in project, and then the bug only appear in export, but sometimes it is also visible in project.

We have tested deleting media cache and render files, and deleting the assets in the project and freshly re-importing them. When re-importing the AE comp, the edited text works fine as expected, but when you duplicate this AE comp and then change one of the part numbers, the bug shows again. Not all AE comps get affected, but so far have only seen two of them "sharing" text information.

It seems that maybe the first time you open the project the text will be fine, but when swapping to another sequence, the text will be swapping from the AE comps in both those sequences you swapped between. We have also observed though, that sometimes the original text of the AE comp will appear again, not just to another edited text in a different sequence.

This error was not present in Premiere 2023, it has only just started showing in 2024. We recently updated some Mac computers from an older version of PP 2024 to 24.6.1, but may have started occuring even later post-update. I'm not 100% sure on this.

Below is an example of what we're seeing:

Any help will be greatly appreciated!
