Hi there!

Sorry for the inconvenience.

Are you talking about Helix3 Version 3.0.1?

If you have tried this latest version already, then you can use the following code in your custom CSS for now:

#offcanvas-toggler {
    margin-top: -90px;
}
div#sp-logo {
    width: 80%;
}
#sp-header .logo {
    height: 90px;
}

Note: Path towards custom CSS: Extensions>Templates>Styles> Click on your current default template name then choose Template Options. Then find custom CSS within the custom code.

Best Regards
