I can’t change the film’s release date

Release date was entered in error. The film was still in post-production in 2023 and was never publicly released, screened, distributed, published online, or shown at a film festival. The 2023 date was mistakenly entered when the title was added to IMDb and does not represent an actual release. The film is being completed in 2026, and I am planning to submit it to film festivals for the first time in 2026.  I can't update the production status to the status that accurately reflects a completed film awaiting its first public or festival screening.

I tried to change the release date to 2026 because I have only now submitted the film to festivals for the first time, but IMDb keeps rejecting the change. What should I do?
