How to remove page links from the header

I am very limited with knowledge of web design. This will be obvious with my question.

My page links are displayed in the header and footer. Unfortunately, in the header, the page links are on the right as well as the shopping cart. They overlap.

How can I remove the page links from the header leaving only the shopping cart?

There is a slider I can click to remove the shopping cart, there must be a slider somewhere where I can remove the page links instead.

Thanks,

You can remove pages from the header navigation by going to the Pages menu in the dashboard and moving the pages to the "not linked" section rather than being in the "main navigation".
