"Replace default primary post meta" button enabled but still shows default

Hi, I have created a new Post meta template for author, date and categories, and the "Replace default primary post meta" is enabled, however the default category links are still showing at the bottom of the page. It's not a big deal but where is this coming from and why is it not now disabled?

Also, is it possible to keep the belowpost navigation that sends viewers to the previous or next post? I have included a post link below for you to see.

Thanks for any help,
Nicola
