change "self" to character name like "dancer"

Hi, 

I appeared on Oprah's (the number one mobile media news site) Now This Next, but (I don't even know how often they come out) everyday, week, month?

And I'm honored (had to fight for this credit) to appear amongst (even though just two seconds) people like Oprah and Hillary Clinton, 

but since it is a "Self" credit, it is way, way down at the bottom and I fear never gets seen. 

And I've tried a few times to get my "self" cred changed to Dancer (because I was dancing in a Jo Jo Siwa video within the program)

but IMDb kept warning and warning me. 

Any suggestions!? Thanks!
