Toggle Menu color in mobile version is different than my settings

Hey,

i have a issue with the toggle menu color in the mobile version.
Somehow the color is different than my settings in customizer.

I dont want it to be orange when its active or clicked. The color i wished on hover is blue with white text. When you click the toggle menu it turns orange sometimes by no reason.

The domain is: Servicetime-berlin.com

Here is a Screenshot

I played around with custom css too, but i didnt work. Here is my css:

.main-navigation.mobile-header-navigation {
background-color: #ffffff!important;
}
.menu-toggle {
color:#3c6fca!important;
}
.menu-toggle:hover {
background-color:#3c6fca!important;
color:#ffffff;
}
.menu-toggle a:active {
background-color:#3c6fca!important;
color:#ffffff;
}
