Hello

Thank you for your query

Kindly add the following css rule in Custom css section:

.logo-slogan {
    padding-left: 10px;
}

Hope this helps you.

Thanks, but where do I find that exactly? I guess clicking on the template until "Templates: Customise (Shaper_helixultimate)" is seen? Or on the server in the database?

You are most welcome. You can kindly check out the link below, this will guide you:

You need to go to Template Options - Custom Code tab.
