As been said many times here. BIAB/Reaper are a wonderful combination. I have never seen the issue you are mentioning, but Reaper can be very complex and folks above have pointed you to some set up features which may help.

Otherwise, I can tell you I don't convert to wav prior to the transfer. It can all be done on the fly with Drag and Drop. That way I keep BIAB open at the same time as Reaper and can go back and forth as needed.
