I don't have any filter but in my General tab, there are 1263 hands, but in my Hands/Positions tabs. There are 1308 hands. I don't understand why. I tried to reimport all my hands, but it didnt change anything.
What version of PT3 are you using? If it's not Beta 16, please update. Do you have any aliases set? Try removing them and see if that helps. What sites are your hands for?
