I have a custom post type called 'Aanbiedingen'. I use a custom field group where I store some information. Via the 'gear icon' on the custom field group I went to the settings page where I made a change (added a input description to an existing field).
When i open one of the custom posts all fields in this custom fields set are empty (see image 1). But when I check the custom fields via the regular custom fields field I see the information is there (image 2). I flushed caches, cleared browser history etc. but the fields stay empty. Any idea what might be the issue?
The info is showing on the front end of my website so I'm sure the info is stored in the database but just doesn't show up in the custom fields in the Meta Box section.
