I have uncolored skulker boxes in chests. I was unable to move them from the slots they were in to my inventory or vise versa. If I break the chest I can pickup the uncolored skulker boxes but then they are stuck in whatever slot in my inventory they land in, and I can't move them out or around.
The only way to get rid of them is to destroy them either by breaking the chest and letting them disappear or killing myself and letting them disappear on the ground.
Because of this behavior all contents of the boxes are lost because you can't place them anywhere to open them.
