Sorry, Your file mover is a mess.
It needs an overhaul and rethink... I tried to move one file into a different group and found the entire process deeply flawed.
There should be only on panel to deal with this, select a file: "from-to" "copy/move"
Clean and simple.
Different columns and situation-reveal tools make for fear based file movement.... for five minutes, I thought my file was erased!
It went into a folder I didn't want, couldn't move to the group I wanted, and filled me with a deep cold dread of moving files in 360.
FIX!!
