unable to merge or delete titles, need help!!!

Hello,

I erroneously uploaded a bunch of titles in which I was in the cast as "videos." It was later brought to my attention that they should have been labeled "TV episodes." I unsuccessfully tried to delete the "video titles," so instead uploaded the same titles as "TV episodes" hoping to either delete the original "video" titles or merge them. I have been unsuccessful at every turn, despite following all the guidelines. I'm at a loss of what to now. I have 19 duplicate titles on my page now, in one place listed as "videos" and the other listed as "episodes." Please help.
