Expression Map Interface Bug (In Key Editor)

When moving a MIDI region from one lane to another, both having different expression maps set, the expression map in the inspector of the Key Editor does not change visually. Even if you try setting it to different expression map settings, it visually remains fixated on the original map you set from it’s original lane. It works functionally however.

Edit: When I copy and paste the same region into the same lane, it appears to go to the correct map.
