I have a problem with a custom SELECT field in WP Admin. This field is not saving or displaying values in the database.
For Choices I have my function "callback: admin_get_exteriors_from_options" and checkbox "Save field value" enabled.
The admin_get_exteriors_from_options function returns array and it's correct displayed. But haven't selected value.
This is the code generated by MetaBox for my custom field.
