Tearing my hair out - I can’t work out why these collection lists are not level despite using the same classes for each column. It’s inside the main menu symbol (desktop only).
My menu is a little different to yours in the read-only link (Or I might be in the wrong place), but I’ll try and give you a hand.
The main fixes are basically through setting a min-height of 35px and then removing the varying padding applied to properties. One of the menu headings had additional padding.
