Hi,

I think there is an error in the CSS for Helix Ultimate. When I select Left for the off-canvas position (Menu > Off-canvas > Off-canvas position) the burger icon is not visible. This is because in CSS the off-canvas is hidden:

body.ltr.offcanvs-position-left .offcanvas-menu {
    left: -300px;
    top: 0;
}

Don't know how to solve it but thought I let you know.
