Strange crossfade error - CB5 Es - I need quick help please!

Hello fellow soundgeeks! :wink:

I’m currently correcting drums in Cubase 5 Essentials and I came across a strange error, which keeps me from finishing my work… Me and my friends are quite experienced users but still, we cant figure this one out.

Since i have to finish 4 tracks by Friday, quick help would be appreciated. :exclamation:

When I’m creating a crossfade in my project, in the crossfade itself a different part of my track appears… I know it is quite hard to imagine, so I made a few screenshots…

I need a quick help. Does anyone know, how to get rid of this? Its driving me crazy… :imp: Everything worked just fine in previous projects.
