Hi!
Oh, okay, I get it now.
By default, there is a maximum row limit to that layout, which is set to 2. After reaching 2 rows, it automatically moves the items to the next ‘page’. This is adjustable on the Theme Options panel. Giving high number of maximum rows (like 100) will skip the pagination: https://i.imgur.com/FBrP3UG.png
That should do the trick 🙂
