Main nav menu order reversed

Never mind. When I started changing the labels of some of the items and it didn’t have any effect, I figured out that something else was fishy. I eventually figured out that I have to add the menu to the “theme location” for it to work. What threw me off is that there is apparently some magically created menu with all your static pages that appears in the main menu location if you haven’t assigned an actual administered menu to it yet.
