Tab CSS breaking on Live site

I’m in need of some design help here. Today is launch day and everything looked fine in the Webflow designer, as it usually does, and then exporting the code the layout breaks. This has happened more than once and it’s very frustrating considering I can’t troubleshoot in the designer, because it looks fine there.

Can anyone point out why the Tab system is breaking on the live site?

Thank you! @Waldo

Can you explain what the issue is please? If you send some screenshots it’ll be better.
