Help with a review requirement ( soft reject )



Anyone had this message and understand what it might mean? The message is “Sidebar does not appear.” with a picture of the metabox for the blog sidebar.

I’ve triple checked it works in different scenarios. So I’m wondering, might it mean it’s supposed to appear on pages as well as posts?

My other thought is if the reviewer wants it to appear when you click preview - I’m not sure I’ve come across any metabox frameworks where metaboxes update the value on preview.

Any ideas?
