Themer Posts (product) Archive not displaying properly after 3rd page of pagination

I currently have a Themer layout that is for a Posts Archive. The content of the posts is to display products. The products are displayed in a 3x3 grid with number pagination at the bottom. The pagination works for pages 1-3 but when i get to the fourth page and beyond (5, 6, 7, etc) it says page not found. I have 36 products so there should be at least four pages of products. If i change the products per page to display 12 and only have three pages it works for those three pages but anything past four pages of pagination does not work. Any insight or help would be appreciated.
