changing BPM bug?

So, I don't know how i get to do this, but sometimes the bpm count of the sequence I'm working on just changes to weird amounts. Usually when I was doing stuff in trim or so.

Anybody else havin' this?

I happened to me with the OS1 until i realized i left the tap tempo on Pad 1... so everytime i used that pad i was changing the tempo... i hope it will help you
