Post Grid

I got the post grid to work on one page: https://thenomadicmango.com/blog/good-eats/

However, when I try it on another page, it shows up once but then when I refresh it goes back to just a regular view. Ex:
https://thenomadicmango.com/category/south-america/colombia/

I deleted my cache plug in. Any other ideas?

The page I need help with: [log in to see the link]
