Menu issues when switching pages

Hey, I used the hamburger menu on all devices. On first Page everything works great, but when I click on a other Menu option, it changes the page, but the background is not there anymore, but the Menu stays open and when I close it, the background appears.

  1. How do I get it, that the Menu closes, when I switch pages
  2. How do I fix it, that the background stays with the Menu options and does not do these cross actions.

I hope it is clear and somebody can help me.

Thanks a lot
