Well your RD track is appearing as a MIDI track .. realdrums are audio. (see image I posted as well as others in this thread; they are generated as audio tracks, not MIDI)
So it's not generating that track correctly for you. The rest of us see an audio track .. you can't assign realdrums to a MIDI track, which is what you are trying to do in the popup in your image.
MIDI is MIDI and audio is audio ..

You could select a blank track and try generating the RDs by themselves .. but for the rest of us it is working as expected.
Maybe try getting the last 2018 update for RB (?)

If you want to test, another thing to try is saving the BiaB file as an SGU file (instead of MGU) .. see if that opens differently in RB.
May want to also make sure RB is pointed to the same folder for the Realdrum source files that BiaB is using; if RB thinks the RD is missing it may resort to substituting a MIDI drum track .. which seems to be happening here. This would be expected behavior if RB can't find the Realdrum source files.
This is in the Options- Preferences - Song Generation tab in RB.
