Tab menu doesn't show on mobile

I’m having trouble with the display of my tabs on mobile > See career (karriere )page. It shows on webflow preview but not on the published site. Instead, it shows all tabs contents. The display settings are all set to flex, width is 100%. I don’t know how to fix this, can someone please point me in the right direction?

Here is my site Read-Only: Webflow - ALVA - PV-Projektpartner für Ihre Immobilie
