Hello,

In order to set capitalize letter for menu, use this CSS:

.woodmart-navigation .item-level-0>a {
    text-transform: none;
}

If you need capitalize letters in Browse Categories as well, use this CSS:

.menu-opener .menu-open-label {
    text-transform: none;
}

If you want to hide the icon in Browse Categories, use this CSS :

.menu-opener > .burger-icon {
    display: none;
}

Best Regards
