Deletion of a misleading exhibition

I'm trying to request a deletion of the following exhibition date--March 19, 2025 (The Monthly Film Festival), in the United Kingdom, for this film: https://www.imdb.com/title/tt29980326/releaseinfo/?ref_=tt_ov_rdat--, but IMDb keeps justifying the refusal to erase it with being unable to verify my contributions.

There was no physical screening in this date and keeping it on IMDb may mislead people into believing the film was actually screened in a theatre in the United Kingdom. The only time it was screened outside of Portugal was in the Pulcinella FilmFestival, in Italy, in the date that appears in the page. All the remaining screenings happened in Portugal.

I'm the director, producer and sole distributor of the film and there's no better source to confirm this information. My only goal here is to correct misleading information and prevent a false sense of "international exposure" that the film didn't achieve.
