Google analytics only tracking checkout pages

[AMcc]

Hi all!

We've recently swapped from using GTM to the in-built shopify google analytics setup. The reason we swapped from GTM to the native solution was that it wasn't tracking sales before. Now luckily we are capturing sales data in google analytics, put in the pages & screens report it is only showing checkout and order confirmed pages? No collection or product pages. 

Does anyone have any idea why this has happened?

Thank you

This is what our analytics looks like - blocked out anything brand related

All pages that aren't checkout pages are (not set)
