Hi there,

Thanks for getting in touch.

Try adjusting with the following custom css. Add it in Salient > General settings > CSS/Script related:

@media only screen and (max-width: 1000px){
   #slide-out-widget-area.fullscreen .inner .widget.widget_nav_menu li a, #slide-out-widget-area.fullscreen .inner .off-canvas-menu-container li a, #slide-out-widget-area.fullscreen-alt .inner .widget.widget_nav_menu li a, #slide-out-widget-area.fullscreen-alt .inner .off-canvas-menu-container li a {
    letter-spacing: 0;
}
}

Kind regards.
