wpDiscuz not working on pages / select content types?

Hi there, I am using wpDiscuz on my site and it works perfectly on all posts. However there are a few pages too where the comments section is enabled and on those pages only the classic WordPress comments section appears.

I thought there may be an option to enable/disable wpDiscuz for other content types as posts, but I can not find it. It should work for posts and pages, right?
