Shopping Cart issue

I am having a problem with the shopping cart not displaying the items properly when the "shopping cart" link is clicked. (see image 1) The cart only display for a second and then scrolls back up before I can click on anything. I am also having issues with the quantity + and - buttons aligning properly. (see images 2 and 3) Finally I am having some conflict with eShop and my Purity III template, whenever I install the eShop on a new dev site, the off-canvas button is modified. (see image 4) Any help with any on these issues would be greatly appreciated. Thanks!

Hello Chris,
All of these issues related to CSS conflict with the template. Please submit a new ticket to EShop category to send me the back-end log-in account to your site so I can help you to resolve all of them.
Hope to receive your ticket soon so I can help.
Sincerely, Giang
