Not sure how to make changes to my new listing or get some info to show

Hi,

I have just started an Amazon selling account and listed my first product, however, I have a number of questions/problems with the listing, if someone coupld please help me with them. I’ll number them below.

1) The product is showing with a shipping charge of £3.99, how do I change or remove this?
I have found shipping settings (I couldn’t actually find it in the menu and instead found it linked via forum post)!
https://sellercentral.amazon.co.uk/sbr/ref=xx_shipset_dnav_xx#shipping_templates
But there is no option to change the price at all.
2) Also, it is not showing the usual price/’add to basket’ option on the right hand side, it simply says ‘See All Buying Options’ and you have to click on that to then see the price and add it to the cart.
3) It doesn’t appear in search results when I put in the exact title of the product. What can I do to change this?
4) Finally, for the Product Description I have added 4 different lines, but it is only displaying the first one that I’ve entered! Any ideas why?
Thank you!!
