Ahh Mobile Header logo is suppose to be a small image or an icon (like the C in CRYO).
If you want to use the normal logo then I would suggest to use the normal header on mobile.
So assuming this is the direction you’ve followed:

Change the CSS to
@media (max-width: 768px) {
.site-header {
display: none;
}
}
Then upload a logo in customizer > Site Identity.
