I'm using a custom template to implement jQuery isotope, and I'm pulling the image tags as a filter menu. The problem is that the slugs of some of the tags show a trailing number (ie. "gymnastics-2") leading me to believe they were duplicates at one point.
I tried editing the slugs in the Manage Tags menu, but they still show as duplicates. I tried dropping the tags in the database and then recreating them, but the duplicate "-2" still shows up.
