Website tweaks needed to shopify site

I need a few amends to my shopify site. Firstly see screenshot attached on mobile, the logo is visible between the products as you scroll down. I need this to be fixed as I don't think it should be visible here.

Secondly I am using an app called 'Shop the look' to display the matching bikini top or bottom for our bikinis. I have added a sarong which has one size only and it is causing some issues with how it is displayed. See attached screenshot. The cart icon button is centred instead of on the right like the other cart icons and the product title is also left aligned instead of centred. I have emailed the developer from the 'shop the look' app and he said it is because of the code attached, the width should be 100%. I need help modifying this so my Sarong item looks the same as the other items.
