They postponed the episode date and I can't correct it on the website

The anime That Time I Got Reincarnated as a Slime had its episodes released before it premiered, but unexpectedly they announced that episode 5 of the third season, which would be released on July 12th, was postponed to July 19th. (https://x.com/ten_sura_anime/status/1812127637252477247)

However, on the website I cannot correct and put the correct date because there would already be a superscript date that would be part of the normal schedule. With the postponement of the previous episode, it is necessary to change the website but my attempts are denied. What to do? Can only Staff fix this? Because now the rest of the episodes will come out with the wrong date on IMDb.

Here is the link to the corrected dates for the next episodes: https://tensura.fandom.com/wiki/Season_3/Episodes 

Here's how it currently looks on the IMDB page: https://www.imdb.com/title/tt9054364/episodes/?season=3

I've tried to include all possible links as a source but they always deny my attempts to correct the dates.
