Year of production incorrect on a documentary

Hi, I have just added a new title to IMDB through the contribution « 210204-212720-990000 ».

It is a documentary from Yann-Arthus Bertrand named « Legacy, notre héritage ».

My contribution was accepted, but the year of production written at the top of IMDB page did not follow what was in my contribution.

Indeed, the movie was produced and directed in 2020 and then released the 26th January of 2021.

So, as indicated in my contribution, you please have to mention 2020 under the title of the movie (and not 2021).

As this information is not available for change on IMDB (even through another contribution), I go to this forum to request the help of an IMDb employee.

Please find hereafter some evidence:

I would also know why this documentary does not appear on the page of the director (when we go on his profile page). I though quoted him as director and he appears like that on the documentary page.
