Problems with mobilemenu i several levels

I use RT theme 19. Suddently, I can not enter subpages in my mobilmenu. I can see all the levels in the hamburger menu but when I press to enter a subpage ( the subpages are product categories if it matters) I just get to the page that was seen at the same place before the hamburger menu folded out. It is hard to describe what I meen, hope anybody understand what I mean an know what to do.
I have been trying to create the menu from scratch but the problem still remains.
