Squarespace 7.1 Mobile Navigation Changing Color

Site URL: https://www.captivantcollection.com/

My mobile site's navigation background suddenly changed from white to black a couple of weeks ago. How do I change it back to a white background with black font? Thank you! 

Add to Home > Design > Custom CSS

@media screen and (max-width:767px) {
.header-menu-bg.theme-bg--primary {
    background: white !important;
}
.header-menu-nav * {
    color: black !important;
}
}

Thank you!
