Problem with categories

Hi @walter723

On the edit page, you’ll sell all of the posts as a demo. The query doesn’t work on the edit page as far to reduce query pressure. If you want to show posts from all of the categories, don’t select anything.

And if you select multiple categories, select by pressing ‘CTRL’ as well.
