Navigation Issue in Uncode Theme

Hi, I have a question regarding navigation within the Uncode theme.
I created two categories of Posts. For each category I created a Index page containing a Masonry Grid.
Within the Page Options → Navigation → Navigation Index, I set this Index page as the Navigation Index.
However when I use the navigation arrows at the bottom of each post, it references ALL posts. And not just the posts within the Index.
Is there anyone with a suggestion.
Thanks, Jorrit
