Slot is moved to another group, AnimBP shows it as DefaultGroup

I made a montage, moved a slot from DefaultGroup to another group, then I set the new slot for the montage. Then I try to add a slot node in AnimBP. It always marked as DefaultGroup no matter what slot I write to it.
Compile didn’t help, save didn’t help, restart didn’t help.
I noticed that changing slot groups affects logic, but does the wrong slot group on the slot node change anything?
