Social Menu Error – class="last-menu-item menu-item-social-media-container"

Hi All,

I’ve created a social menu using a custom link to my facebook page however it is displaying the following code before and after the navigation label:

class=”last-menu-item menu-item-social-media-container”

I’ve tested creating a social menu using a page instead of a custom link and it still displays this code. Can anyone help advise how I can hide it?
