Stop a header repeat

Good morning,

Here’s my site:

http://www.ansenjie.com/our-products/

I added a bunch of white space in because if I don’t, the header repeats itself. If you maximize your browser window, you can likely see the header starting to repeat itself below the footer. Honestly, I wish there was a way I didn’t even need this page, but I was told our navbar depends on being able to click navbar links (versus only the dropdowns, which I would prefer)

Anyway, can anyone tell me what code to edit so I may prevent the header repeats? All the blank white space looks pretty ugly.

Thank you for your help.
