Paging broken for only one category

We have a pretty full site that unfortunately i cannot link to yet. It’s only a soft launch. In short, one of the categories has “next page” links working but the other doesn’t.

https://www.domain.com/category-one/page/2/ (works)
https://www.domain.com/category-two/page/2/ (doesn’t work)

Any ideas on what I might check for on my end? It may be something to do with the theme but not 100% sure yet.
