Thank you for your patience.

I don’t have a solution at the moment, as I’m not as intimately familiar with CMB2 as needed for this issue. I have pinpointed it to this line though:

$sanitized_values = $cmb->get_sanitized_values( $_POST );

Here’s the get_sanitized_values() method:

https://github.com/WebDevStudios/CMB2/blob/master/includes/CMB2.php#L438-L465

For whatever reason, line 457 is not returning the category key as part of the array and thus it’s not present in your callback for processing and saving.

Any changes or discoveries with this one aumsrini?
