Group grid view throws in empty spaces while displaying groups

I noticed that ROBLOX re-added the group grid view to profiles. Since I’m not in enough groups for it to actually matter, I used Lilly’s profile to check how usable it was. It seemed fine at first, but as I kept loading more this happened:

(I zoomed out after I had loaded all of those – I was at normal zoom while clicking load more)

I only get it on the profile page (not other pages) and it’s displayed as soon as I load the page (not when I load more groups), so I’m not sure if it’s related. I’m not using any extensions.
