Unable to add episode for "Na sygnale" – missing later seasons block submission

I am trying to add a credit for a Polish TV series "Na sygnale", but I am unable to proceed due to missing seasons in the IMDb database.

The issue is the following:

– The series currently has only 13 seasons listed on IMDb– The episode I am trying to add belongs to a later season (S20E893, titled "To nic śmiesznego")– Because these later seasons are not present in IMDb, I attempted to submit the episode myself

However:

– My episode submission has been repeatedly declined due to “lack of evidence”– I have already provided multiple forms of verification (contract, call sheet, script extract, end credits, and links to publicly available sources such as TVP VOD, Wikipedia, and Filmweb)– Without an approved episode, I am unable to add my credit (role: Mariola)

At this point, I am stuck in a loop:– I cannot add my credit without the episode– I cannot get the episode approved despite providing standard industry evidence

It seems the issue is not the lack of evidence, but the fact that later seasons of the series are not yet included in IMDb.

Could someone advise how to proceed in this situation, or forward this case for manual review?
