So the hover color isn’t working for that menu item?

This happens when the menu item is set to current. The current menu item has no hover.

Of course, you can overwrite this with CSS:

.main-navigation .main-nav ul .current-menu-item > a:hover {
    background: red;
    color: #FFFFFF;
}

.main-navigation .main-nav ul ul .current-menu-item > a:hover,
.main-navigation .main-nav ul ul .current-menu-parent > a:hover {
    background: red;
    color: #FFFFFF;
}
