Poker tracker question (I don't think this is the right area)

[spivey]

I could not really tell which forum to post this in, so I'll understand if it's moved...

I just got poker tracker today, and there are a couple of things I'm not sure how to do.

One is if there is a way to de-import hands. For example, all of my .10/.25 hands so only the .25/.50 hands show up.

The other question is why would I have a negative BB/hand rate when I have won money according to poker tracker.
