Footer on category pages is only partially displayed

Hey Friends,
there are 3 columns with posts in my footer. Posts from CPTs are displayed in 2 of the columns: https://wordpress-werkstatt.de/

When I go to a category page, only 1 post is displayed and no posts from CPTs: Backup » WordPress Werkstatt

Do you have any idea why this could be?

I found the solution. This option must be activated.
