Unable to edit false and incorrect credits

Hey there, I'm the co-creator and series director (season 1 and 2) of the animated preschool TV show Milo (2021). This is the IMDB link to the show: https://www.imdb.com/title/tt15655602/?ref_=ra_gb_ln?ref_=ra_dc_ln A whole load of credits have been changed and added for folks who didn't work on the show at all and in other cases some people are claiming credit which isn't theirs to claim. It's all within the producers section of the credits but when I go to submit an edit online I can only see my pal Joe Moroney - who WAS the producer for those series. The other people claiming credit don't show up. Any suggestions on how to fix the issue and keep it that way? Thanks! All of the episodes are available in the UK on Channel 5's My5 website. If that's geoblocked for you I can provide proof as me and the Editor, Mike, worked up and checked every episode's credits during production.
