I'm the director of the film and can't change/delete the release date - Reason Unable to verify.

Hi,
I'm the director and producer of the film and can't change/delete the release date - Reason Unable to verify.

https://www.imdb.com/title/tt14247822/releaseinfo?ref_=ttpl_ql_dt_2

I've submitted an edit and got the below message. I went to the "Contribution History" page and tried to delete/change the date,  provided the explanation.

Can someone help me how to delete my release date? Still release dates are not finalised.

@Michelle can you please help me and delete release date?   

Thank's in advance.
