Want to move files but they still remains at the same place...

I wanted to move my files into a folder with the "move" button but after done that more than once it's not working.. When I'm refreshing the page nothing have change and files remains at the same place.

I think it's a bug or smthg because I never have such thing.

And please update the drag and drop when we want to move files into a folder it's much easier !
