Horizonal Categories, Should be vertical

For some reason the categories in my top navigation bar are expanding horizontally on hover over when I believe they're supposed to be vertical.

Site is: https://www.maximalperformance.com/opencart/index.php (still setting it up, ignore the other issues)

Any ideas on how to fix this? I originally had 1.5 installed and the same thing was happening there.

Revert the changes to header.tpl. You clearly made some changes there. The menu structure is different from original

Have your edited it?
Login as admin-> catalog-> categories ->your categories-> edit->data-> column ->....-> Save

***ONLY work for top parent categories***

I didn't edit it which is why I was confused and it happened on multiple installs.

That's it, thanks! The migration (I used cart2cart) must have carried over that value somehow, it was set to 92. Changed it to 2 and it works great now. Thanks again!
