All menu items visible on mobile/tablet

I need to create a web site with two locations. Every location needs its own set of pages witch are basicly the same, but contain different content. I have created one menu that contains all pages, pages for one location, and pages for the other. In my case your plugin was ideal for me ’cause on the pages of the 1st location I needed to hide all pages from second location, and contrary, and it works fine.

The problem happens when I switch to tablet or/and mobile view mode. When i switch to different mode or resize browser all menu items that were hidden are now visible.

Thank you for help.
Great plugin, by the way!
