Festival Release Date Correction Not Working

Hello, IMDb or anybody else reading this. There has been a problem with correcting festival release dates for a few weeks now. Previously this has worked fine, but now the data editors won't accept it even if I paid attention to that I got everything on the submission guidelines right. Even if I re-submit it it doesn't seem to work.

An example: I tried changing the festival name attribute of the film Paradaiz [link=tt38998475] from the name "Filmfest Dresden" to the more commonly used "Dresden Film Festival". It accepted it and I waited, but when I returned the attribute hadn't changed. I looked at my Contribution History and it said that "it did not follow the guidelines" even if I did make sure it followed all the guidelines. I re-submitted it but the same thing happened. Same is for "premiere" attributes.

I hope somebody knows a solution and could help me.

Thanks for reading.      -Venus
