Unwanted pre roll in Waves Tune

I like the plugin a lot. I always start rewire plugin before using Tune. I cant figure how to set the cursors to start at the same spot as ProtTools. I have tried everything to solve this. It seemes that sometimes the cursors jump several bars ahead and out of the window i´m working in. It´s like the pre roll function in PT is set. It´s annoying because i cant find out where tu adjust it. Can anyone tell me how to solve this problem? Maybe it´s easy to fix, but not for me:)
