I installed easy populate and I had a few categories named October 2012, September 2012, etc.
Excell changed them to Oct-12 and some of them to 12-Oct and now I have multiple categories. They seemed to be linked together so If I disable one then they all disappear. I am afraid to delete the any of them because I feel like it might delete the master category as well. Also when I go to the update multiple category manager the other two are bold.

How can I unlink them so I can just disable one without disabling the master as well.

Thanks in advance
Any help is appreciated
