Fill Gaps Between Selected Items actions break later crossfades

[mtierneymusic]

When I use the "Fill Gaps..." actions now, they break the crossfade after the ones I'm trying to fill. I made a little gif to show it–I'm using "SWS/AW: Fill gaps between selected items (advanced, use last settings)" for the sake of convenience. It's working perfectly on the crossfade between the two selected items like it should, but then the crossfade on the right gets ruined.

Thank you!
