Desktop Menu Bug

Hello everyone,
I’m having a bug with our nav bar / Menu. https://www.pathway-solutions.de/ It disappears on desktop even after I publish the settings “menu → show”

once I publish the theme it seem’s to reset the settings and the menu on desktop is gone again:

I tried to restore to a former backup from two weeks ago already when our menu was working, but even then I experience the same problem. Is this a known bug?
