I was able to get this working by moving a line of code around. On line 627 of verve-meta-boxes.php I moved “delete_post_meta($post_id, $key);” outside of the if statement so that it will always delete the existing data. Then, it will save if needed in the following if statement.
PS – I am not a WP guy and have not spent more than 30 seconds on this so use at your own risk.
