File list disappears with drag and drop to Mixed in Key

I saw this post, However, I'm only seeing this with one application which is weird. I can drag and drop to other applications and the issue does not happen. It's only when I drag the list to Mixed In Key for processing. Link: https://mixedinkey.com/ The list will disappear and I can will refresh after.
