I was the OP in the Sonar group. The issue has been resolved. Both BIAB and Sonar at "fault" IMO. If you can call it a fault.

"Include ACID info" should be off as a default in BIAB IMO but it is on.

"Default Groove Clip Pitch" should be "None" in Sonar IMO but it is set to C as the default.

Either, or both changes would fix the problem.

In any case, now we know and it's not a big deal.
