So you're using mbox format. It doesn't support folders that have mails and subfolders. So either

a) Switch to maildir format and everything will work as you expect

b) When you want to create a folder that can have subfolders, create e.g. "foo/", with the trailing / character. Or you could directly just create "foo/bar" without foo even existing.

The folder deletion is probably also because of TB stupidness. http://wiki.dovecot.org/Clients#Thunderbird
