Duplicate and rename class are broken/bugged out

On the Plugshare page, there are 4 modals on the root. The last 3 ones can’t seem to be edited. Duplicate doesn’t seem to do anything while trying to rename one will say the class name already exists regardless of what name you try to add.

Here’s a link to the issue:

No response from the dev team? It’s a very obvious bug.
