Hi there!

Thanks for contacting us.

Have you updated your template version, please?

However, the following code in your custom CSS should help:

#sp-header .row {
    display: flex;
}
div#sp-menu {
    flex: auto;
}

Here is all about custom code placement in Helix3 framework: https://www.joomshaper.com/documentation/helix-framework/helix3/custom-css-header-code
