Tabs background error on upfront

Good morning guys, I am having an error in the "tabs" draggable element. Originally when I was first setting them up, the tabs had a transparent background and the tab title would bold to allow the user to know the current tab selection. I am not sure what I may have done, but even when I add a whole new tab, the background is grayish and the tabs no longer bold. I appreciate any insights you guys may have on this. I ve also included a screenshot, screencast , and an example link to help. Thank you for your time.
