Columns Wrapping

My new site was working well for layout and now for some reason the columns are wrapping for no reason that I can tell. The 3rd column drops to a new line.

I’m using Divi for a theme and it’s setting seem right, and I’ll post to their forum, as well, but I’ve seem related issues on this forum (though none with answers that worked).

This happens across multiple pages.
Thanks in advance for any ideas, group!
