There is a very serious problem, but I do not know if I can tell.
When I want to update a post, it does not accept all of the previously selected ones from the CPT custom fields, and does not accept updates when I click the Update button. But if at least one of them is marked, he accepts the update.
To open a new support ticket, first select the relevant forum and then click the "New Post" button. Example: You need support for the core plugin? Click on Core Plugin support and click on the "New Post" Button.
