I'm on build 145 now, and today I had the same tempo-reversion issue that I reported earlier. (And this behavior is new, as of 2021.04)
Create a new project using File | New and the basic template I always use
Input name, bpm, sample rate into the resulting dialog - the project opens in CbB (note that the tempo is as I assigned)
Save
Import all audio files via File | Import | Audio - tempo remains as I assigned
In track view, click (on the track number, just left of the track name and icon) to select one of the audio tracks ...
Note that now the tempo has reverted to 100 bpm. Previously, I thought it was after I assigned the selected track to a track folder; but it actually happens as soon as I select a track in the interface.
So, to correct, I:
Return the Now marker to 1:01:000
Reset the tempo to my original assignment
Re-save the project
Now the tempo "sticks" and is undisturbed when I start to work in Track View.
Of the four mix projects on which I experienced this behavior, three were from Dueling Mixes and today's was from pureMix. I don't really think it's the audio files ...

Update 5/25/21 -- downloaded and installed 2021.04, build 175, perhaps a week ago. This tempo-changing issue hasn't happened on the new build (and I've imported another 3 projects, since the new install). Thanks, guys!
