I'm out of storage in basic and tried following the instructions to leave a shared folder. I'm not the owner, but when I get to the menu for who can access I don't have a dropdown by the "can edit", it just says "can edit". The other people who can access have a drop down as does the owner. Is this trying to tell me something? The screen shot has been redacted for privacy reasons. I am "Alan", the Owner is further down the list and not shown.

[I'm finding the way that someone sharing something with me can totally lock up my dropbox as out of space is quite annoying; especially when I cannot
