Cubase 12.0.60 Bug in Track Import

I conduct a track import, ‘Channel & Inspector Setting’ only.

I assign source audio tracks to the target audio tracks.

One of the source & target tracks is disabled. Not sure if this is a part of the problem.

The import appears to have worked, but the import alignment is broken and tracks no longer play back properly. Soloing individual tracks gives incorrect results; snare mic has become kick mic, hat mic has become ride mic, etc. - even though the track waveforms look correct.

I can recreate this consistently.
