Repeating Products (Storefront Theme)

1.On the product page, I have duplicated items. Please take a look at https://istitchdezigns.com/cubbies-2/ torwards the bottom. It’s right under the sorting dropdown which is not needed either. Is there a CSS to hide this? It looks sloppy.

2.When customer places order it reduces inventory by 2 instead of 1. How can I fix this?

3. Last this my design button on this page doesn’t match the rest of the pages. Need to fix this too.

Thank you in advance.
