Two CC cloud account mixed up

Originally me wife and I had one (free) CC account, and we both used it from the same computer. We use it to synch folders and files from our desktop and it has worked well - although it is getting full. Recently we tried to create two separate accounts, one for ´Steve´ with a dedicated e-mail address; and one for `Anne´ with a (different) dedicated e-mail address. We then deleted all folders and files from the Anne account. Now, when we log onto the web view, we are told that the Anne account is 94% full, despite the fact that it has NO folders and files.  When we log onto the web view we are told that the Steve account is 94% full (which it is) and it has lots of folders and files. It seems, somehow, that the two accounts ARE not separate. We thought of c~losing both accounts and starting again with two new ones, but are afraid that new accounts will not work with ols e-mail addresses and we don´t want to have to get new e-mail addresses just for this purpose. Any ideas?
