Hi - have logged this as a problem but this is actually a solution for a problem I was having in case it helps others. In Pro for windows, when using the tap BPM it was getting saved into the library with the new BPM and was not correcting - even using reset function, or deleting all metadata folders. But I have found how to do it. Drag the track into the deck, click the drop down arrow and this generally snaps back to the correct BPM (although it doesn’t fix it in the library so stays broken the next time you do it). However, half it, then double it and voila - it is showing the correct BPM again in the library. You’re welcome.
