Category pages not showing questions

After selecting “Categories” in the main AnsPress menu, I am presented with a list of categories. Each categories shows a correct number of questions in that category.
If I select a category, I’m taken to a page like https://mmdvm.com/questions/categories/hw/. This page shows the category name, but it does not show any of the questions in the category. How do I fix this?
Yes, the category page as the [anspress] short code.
For reference, I am running AnsPress version 4.4.4 and WordPress 6.8.2.
