Trying to prove a negative for deletion of uncredited cast credit in episode of Disney's Electric Bloom

Hello, Would a data editor look into contribution 251017-024847-301000. I am trying to delete an incorrect cast credit for episode 1.12 How We Pulled a Song Out of Our Pocket of the Disney show Electric Bloom. The actor actually appears in the show's next episode 1.13 "How We Tried to Crash a Party" but his appearance hass been added to episode 1.12. I submitted a separate contribution 251013-015004-081000 that has been accepted adding the actor to episode 1.13 where he actually does appear but removing his incorrect credit from 1.12 is proving tricky, I think, because the credit has an "uncredited" attribution attached to it, and it is hard to prove the actor does NOT appear in the episode since credit evidence only shows who is credited, not who is not credited. Obviously, it's not practical, let alone legal, to try to submit the entire episode 1.12 as evidence that the actor does not appear, not even in an uncredited role, in the episode. I have re-submitted a revised contribution with the following pieces of evidence to try to persuade that the credit from 1.12 should be deleted: 1) a video clip of the end credits from episode 1.12 showing the actor is not credited; 2) an photo of the end credits from episode 1.12 also showing the actor is not credited; 3) a video clip from episode 1.13 showing his speaking role appearance in the episode; and 4) a photo of the end credits from episode 1.13 showing his credit for that episode. Thank you for your attention to my request.
