Folder tags are shown twice

Everything works but there is kinda visual bug:

I've placed my forms into a folder there in My Forms directory. Nothing happened (probably the browser & connectoion were slow). Then I repeated the action. Since then I had two same folder tags (as in the image below) being showed first and then being replaced as one tag in a second

Interesting bug. I opened a bug report about it. Thanks for reporting it. 

Removing them from folder and re-adding them fixed the problem.
