It’s because the light logo takes precedent – we’ll see if we can adjust that for a future update.
For the mobile logo override, add this css:
.logo-alt-version #mobile-logo img.alt-logo {
display: none!important;
}
.logo-alt-version #mobile-logo img.standard {
display: inline-block!important;
}
@media
only screen and (-webkit-min-device-pixel-ratio: 2),
only screen and ( min--moz-device-pixel-ratio: 2),
only screen and ( -o-min-device-pixel-ratio: 2/1),
only screen and ( min-device-pixel-ratio: 2),
only screen and ( min-resolution: 192dpi),
only screen and ( min-resolution: 2dppx) {
.logo-alt-version #mobile-logo img.standard {
display: inline-block!important;
}
.logo-alt-version #mobile-logo img.retina {
display: inline-block!important;
}
}
