CMS collection only shows content in two out of three columns

Hi! I’m trying to build a CMS page for artists where I display their art. I want to have three columns on the page which seems to work fine when I’m not using a filter but since I only want to show the art of the current artist, I need to use a filter.

So the problem is: when I am using a filter, content only shows in the first two columns, and I can’t get my head around why, and how to solve it.

I would appreciate any tips on how to make the content show in all columns!
