CSV Data-driven Animation Templates randomly not updating text when exporting in AME

Hi,

I might be asking something too specific, but I've had repeated instances (across MacOS BigSur and Windows 10 - latest version) when using data-driven animations that I need to create on a daily basis (about 25 versions per day) with .csv files.

Sometimes, the text doesn't update and it leaves the deflaut placeholders (see below for incorrect data), even though it works with other animations. 

Then, if I try and re-export the same "faulty" comp, it can either repeat the issue or fix it (see below for the correct version), quite randomly.

All the while the updated data show up fine in After Effects, this is really an AME-centric issue.

I am planning to fully automate these daily exports, and such a seemingly random bug would throw a massive wrench in the gears.

Has anyone else experienced such issues and has any fix been found?

Thanks very much for you help.

Note: Changes to the .csv files are done in Excel (both for Mac and Windows) and are saved and closed before opening the AE file.
