I'm having a similar problem in the main 2021 programme.
Most of my files slow down by a 8 or 10 BPM over the last 4 bars using F5 Bar Settings.
When I drag-n-drop a RealTrack into DAW when first generated it's ok, but if I allow the song to loop, subsequent drag-n-drops seem to follow the last entered tempo. This only started with 2012.

edit;
I've just reported this to support.
