I have tried for years to get TCM to remove my name from a movie I was in

I realize that this is IMDB. I can't get through to TCM that on my resume they have listed a movie call "Naked Acts". That Leslie Hoffman is Leslie Hoffman (III) here, I am Leslie Hoffman (I). Also if you go to "Naked Acts" here on IMDB...in the credits it only says Leslie Hoffman. How can I get IMDB to add (III)? If people do not click on the name, they can easily assume that it is a credit for me.
