Editors unusable - whats going on??

Hey, I bought Edocman and try to add some docs but in Details view of a document only the first editor is visible, then follows a long thin "line" of editors, which must be some mistake. What's up here, and how can this be fixed? See screenshot, I don't know how to describe it...

Hi,
It's very strange, please submit ticket and send your site url with super admin account. We will check the issue for you.
Thanks
