Uncredited title

I'm credited as the director of the following video: https://www.imdb.com/title/tt36953030/?ref_=nv_sr_srsg_0_tt_1_nm_0_in_0_q_festival%2520inquieto%25202022, which is true, but my name doesn't appear on-screen.

I've tried to correct it as an uncredited title, but IMDb rejected it. Here's the evidence that I don't appear in the video: https://vimeo.com/1000536251?fl=pl&fe=sh
