Yeah it’s a bug, it’s also killed your stereo reverb plug-in if you notice. Happens whenever you try to commit a mono track “up to this insert” with a stereo plugin further down. Been like this since the feature was implemented.
Basically you have to take your stereo plugin off the track (move it to a dummy track maybe), consolidate up to insert, and then re-insert the stereo plugin on the commited track.
The first time I got caught with that was a air-turning-blue kind of day
