I have a custom field group that I have previously overwritten when transfering a local environment to a staging server, however the old values for this group still apply. When I edit a page or post that uses the group I see the old values. But when I edit the group under the ACF tab I see the new values. Trying and changing any settings for the group has no effect. Any ideas as to why this is happening? Could there still be some sort of duplicate reference left in the db? Note that the site is a WP multisite.
