Sounds like something they have missed, so hopefully there should be a fix.
Workaround:
You could load the actual RealDrum wma/wav in another instance of Biab (set in preferences to run 2 instances) set to the half-time tempo,
then File > Import > Import audio (the RealDrum)
Audio menu > Set audio master (base) tempo to the actual original Drum tempo so it will adjust it to the half-time tempo
open Audio Edit window and go to the end of the track and there will be hits, just highlight the one you want and copy.

In the other Biab with your song move the Drum track to a Performance track then move it to the Audio track
in the Audio Edit window turn Snap on and paste (or in the Edit menu "Paste (mix)" to merge the hit) where you want,
to remove the section that should be held just highlight and cut.
When done move back to Performance track.
