My Meta Box field values are not saving after switching the post type. I am trying to reorganize a website that had 3 separate post types. They had the same custom fields, so I tried to merge them. After switching the posts from the 3 post type to a new one (to have them all in), the field values were gone. So I decided to add the values one-by-one (it is really work-some by the way), but after updating the post, the values are gone. The stack is Bricks Builder, Meta Box, Polylang. I have all the exact same setup for the new post type, as the old post types had.
