About category issues

Hi , I deleted some poll categories but now when i tried to add those categories , it won't let me and a message popped up  "Category named 'Golf' already exists" . Should i have to delete them from database manually ? . I have also cleaned up the cache but the problem is still there.

you should not have to remove from the database, but seems something of a glitch here. what version are you on.

as this would need to be tested and submitted as a bug, if in fact it can be replicated.

I am using latest version dolphin 7.0 and ya it'd we great if you guys can release an update of this to fix this bug.

I also have the same problem when trying to add categories.  Is there a fix for this issue?

so , is this bug has been solved or not
