Hi Tony,

Try following css:

body[data-header-format="left-header"] #top nav >ul >li >a, body[data-header-format="left-header"] #header-outer[data-lhe="animated_underline"] #top nav >ul >li >a, body[data-header-format="left-header"] #header-outer:not([data-lhe="animated_underline"]) #top nav ul li[class*="button_solid_color"] a:hover, body[data-header-format="left-header"] #header-outer:not([data-lhe="animated_underline"]) #top nav ul li[class*="button_bordered"] a:hover {
    width: inherit;
    text-align: center;
}

Kind regards.
