Thanks Mac. I would tend to agree. Perhaps I can dig into the manual deeper and find how to do this.

My solution for now is to export at 120 then adjust to the tempo I need in the looper. An extra step but it works fine.

I seem to have several issues with the wav rendering in BiaB. I have to add two measures at the end of every song because the program chops two measures during render. The other is if I uncheck the box include the two bar intro, it cuts two bars off the front end.
I have to import the file into cubase and cut the two measures out manually.

Still, despite these minor glitches, BiaB is a great program.
