Not displaying all products

Hi,

I’ve just installed this slider, I have about 6 dummy products to test with.
It’s displaying only 4 and when my website is at full width the arrows disappear.
I want the arrows to permanently sit there. So users can scroll between say 16 products etc.

It’s great for the responsive part but as I said full width it’s not displaying.

So basically that, and why is it only sliding 4 of the products instead of the 6?

My URL is: http://therooflightsuperstore.co.uk/dev/

The slider is on the home page.

Kind Regards,

Sadie
