Doesn´t work with categorys applied to pages

Hi,

thank you for the plugin! I am using additional the plugin Add Category to Pages.

Now the plugin has stopped working. The subpages don´t appear or will just be displayed on the top level (not as a submenu).

Here screenshots of the settings I have tried:

Have you an idea, how to fix this?

Thanks in advance!
