Attachments- can't click - bug

Hello @mbatz,
i wanted upload some file to object but i can’t.
When i clicked tab ATTACHMENTS this module moving some pixel on the left every time when i clicked it. I can’t open window with attachments.

I think that this bug occurs when types and object still existed before update to 1.4.1.
If i created new type and objects inside it after update to version 1.4.1 I was able to attach files. However if i tried add file for object in type which existed before update i can’t.
