The issue does not show up in BAIB 2011.5 (internally) at all.
The bug only shows up when rendering to drag the files to an external DAW. (DAW plug-in Mode)

The error occurs around the point that a change in tempo has been inserted (again only in the exported files) (done with Bar setting tempo change)
Tempo changes for example 72-76 or 73-75, so relatively small changes will trigger it.
Yes the files are being rendered to WAV file format for import into a DAW via drag and drop.

I have 2 bar lead in off but it will do it either way
Everything is default I think.
The support person replicated it very quickly.

Thanks
