No pagination arrows when viewing blog posts by tag or category

Describe the bug

To Reproduce
View example at https://howisjt.com/categories/travel/ "paginate" variable set to 4.

Expected behavior
There are more than 4 posts matching this category so it is desirable for the "next" and "back" arrows to appear in the header.

Screenshots
See it live at howisjt.com. Arrows appear on homepage header, but don't reappear if you click a category or tag with more than 4 posts associated with it.

Additional context
