I just notices that my post grids just show all posts on my website now rather than the categories that I linked with them before. For instance the Namibia post now also shows posts under the category of USA. I can no longer change the categories in the Edit post grid option - how can I make sure each post grid again only shows the posts that were linked to a specifc category?
