Hi there Elephant team.
I've been having this bug for a while, but never got around to reporting it, but I thought it was about time.
I play on Titan, and at the end of every hand, my graph does this:
If I reset it, it's fine until the end of the next hand, then it does it again. It only happens when I have both BB and $ enabled.
Hope you can fix it, as it's been annoying me for quite some time now.
