form-required prevents updating an event or booking

Hallo

I am having issue updating past events or creating a new bookings.
I try to save but the timestampdiv element turns red and I can not save.

Example here Screenshot

After clicking publish or update the url get bloated like this
https://localhost/wp-admin/post-new.php?post_type=mec-books&wp-post-new-reload=true&wp-post-new-reload=true&wp-post-new-reload=true&wp-post-new-reload=true&wp-post-new-reload=true&wp-post-new-reload=true

With many “wp-post-new-reload=true”

This issue is random I can reload the page 2 or 3 times then it will finally save with the exact same information added to the booking. I cant determine why this happens

Please advise?

EDIT im using version 6.6.5

Thanks Olan
