Need to remove a release date for two films

I have two films that I need to remove release dates for at the distributor's request. One film was only released at a film festival. I have since deleted the film festival date.  The other film was never released at all not sure how or who entered a release date for the movie.

Teenage Girl: Valerie's Holiday https://www.imdb.com/title/tt8835626

#210111-172840-757000 - removal of film festival release date

The Green Ghost https://www.imdb.com/title/tt4012916/

Thanks,
