Grid content not spanning columns

I’ve got 12 total collection items that I want to display in a 4 x 3 grid. I have the four columns set up with auto-rows, but all 12 items keep stacking in the first column… no matter what I tr.

Most of the posts on the topic are years old and the video I found has an interface from a while ago that is no longer accurate. It seems like such a small thing but I’m really struggling to figure it out. Thanks!

Here’s the wireframe site where I’m working - https://stage-connexpay-marketing.webflow.io (It’s the third section on the page)

Welcome,
The community will need your share link to investigate.

Have you typed “3” into the rows field rather than a 1?
