This indicates that SEF Advance is pulling wrong Itemid from database or no Itemid at all. Make sure that you add all sections (listings or blogs) to main menu. If you don't want them to show you can unpublish them but they must be there.
Also make sure that you don't have duplicate items in the menu. It can happen that you have same links in different menus (e.g. mainmenu and topmenu). In this case delete duplicates and use ordinary relative URLs instead.
Make sure that you empty the trash too as some duplicates may exist there as well.
