Sorry for a stupid question.
In "Session by Day" tab, the lower half of the screen shows hands with columns Time/Cards/Line etc.
In the column "Net won" display shows "05" instead of "$5.16" etc.
I assume I must have clicked something but can't figure out what help?
Edit: It seems to have fixed itself after restart. Damned if I know what happened there, I didn't see any buttons that I may have clicked.
