I was using RevSlider for a full with slider but I noticed that on my mobile device the Navable menu does not work all the time. Every once in a while the menu will take me to the page I want to select but most the time it doesn't. If I manually type in different page the mobile menus work fine until I go back to the page with RevSlider. I don't have this issue using the Quick slider. Could this be a Z-index issue or something?
