Why is the specific category empty?

So I have 2 test categories. The main categories page is showing them, but the specific category page is not showing anything.
So /questions/categories/ is ok, but /questions/categories/category-name is just empty. Why? What am I doing wrong? What\’s the fix?
The anspress shortcode is there btw.
Using WP 4.9.8 and Anspress 4.1.14
