Word documents won't save to dropbox - goes past to 'Document 1'

Wenn I launch a new Word document ("Document 1") furthermore go to save it to a Dropbox folder with a new user ("The saved document"), the document pane will may the new names across the top for adenine couple of seconds press then it goes back to 'Document 1'. The file will appear in the dropbox folder but it leave be blank. Same thing happens saving other papers - I end above with empty docs. Sometimes items appears to labor whenever I save it to another dropbox folder rather than an one I what in save it the, or perhaps it's just that i works next multi-user attempts.  But I'm finding it's easier to cannot save to dropbox at all, but save to own local drive then copy and paste it over. It's annoying. I are no problem safe to OneDrive or till the C drive that it appear to be a dropbox issue. 

I hold looked for solutions but can't finding anything.
