Mobile showing tabs feature on site, but Desktop only shows buttons.

Hi! First time posting here, and also my first website ?? I created a series of tabs for folks to click on various service options and see a description. It works great in the previews and it also works well on mobile. On Desktop, it only shows the buttons. What am I doing wrong? Open to ideas! I’ve deleted the cache a few times. Thanks!
