Big thick lines in between widgets

Hi There

I would like to find out if there is any way to remove this black thick line just above the button by any chance?

My URL is:

Many thanks

Hello there,

Could you plase take wider screenshot, so I can exactly get where that line is located? Does it present on homepage? I didn’t find any button that reads “Get Started” on there. I really didn’t know which code to suggest at this time.
