Page order in menu

I’m totally disappointed.
The header of my blog (https://www.vladzima.com) contains pages menu, which is currently sorted by menu_order&title_li. The problem is I want the pages to be sorted MY WAY, ex. About, Photos etc. What should I do? Changing sort type to id didn’t help much, because I can’t change id’s. Is there any way to solve the problem?..
