This plugin is for generating lists only, it does not alter any WordPress features. When you navigate to a post’s page you just view that post, the plugin does nothing at this point, it only provided the link. The next/previous links are provided by your theme, using built-in WP features, by default they cycle through posts chronologically and there are no easy ways to customize this.
However, recently another user tried to achieve the same goal and succeeded, refer to this thread: https://www.ads-software.com/support/topic/how-to-deal-with-next-prev-links-on-single-post-page/
