how to remove inaccurate credits from my profile

I work as a film/tv editor and I have a profile on imdb: https://www.imdb.com/name/nm0040734/

There are some inaccurate credits I'd like to remove. When I try to edit my page, my edits are rejected because I don't have proof that I didn't work on these shows. How do I resolve this issue? Thanks.

Here are the inaccurate credits I'd like to remove:

"Song Sung Blue" - Art Department [I didn't work on this film]
"Digger" - Visual Effects [I didn't work on this film]
"A Cinnamon Roll Story" - Sound [I didn't work on this film]
