After region is renamed and disappeared, region can be grabbed and moved, thus making the name reappear in the Editor List box, but this is definitely not an ideal solution, just stating for debug purposes.

The name may be made to return in the Editor List box by grabbing and moving the region after it has been renamed and vanished. However, this is not the best way to do it and is just mentioned for debugging purposes.

After Session is saved, closed, and reopened, the regions will appear in the editor list, and can be renamed. After adding additional MIDI tracks and renaming region on that new track, the region name disappears for that region on the new MIDI track.

This bug also affects copy and pasted regions. They will not show in editor list until project is closed and reopened.
