My drop-down menu background has suddenly turned blue

The background of my drop-down menu has suddenly turned blue. I haven’t made any changes to the theme or colors, no idea how this happened. I am using Buddha MegaMenu app, I will attach a screenshot of both the app’s color settings as well as my theme (Simple) color settings. Can’t seem to find where it’s making it blue.

This is the spot to customize menu colors in Buddha MegaMenu app… no blue here

These are the colors for the Simple theme. No blue here either, no idea where it’s coming from. It wasn’t like this before and I’ve made NO changes since I originally published the theme.

ul.mm-submenu.tree.small.mm-last-level.submenu-opened.height-transition {
    background: #fff !important;
}
.vertical-mega-menu ul.mm-submenu, .vertical-mega-menu ul.mm-submenu h3, .vertical-mega-menu ul.mm-submenu li a, .vertical-mega-menu ul.mm-submenu span, .vertical-mega-menu ul.mm-submenu>li>a>.toggle-menu-btn>.fa {
    color: #000 !important;
}

Add this css at the bottom of
Online Store->Theme->Edit code->Assets->theme.scss.liquid

When I do that it also turns the text white, I can’t see what’s in the drop-down unless I hover over each item.
