Black Box in top right of Summary Block images

Hey,

First time posting- I have a Summary block that I want to use to pull a small selection from my 'paintings' shop page for the home page. Problem is these little black boxes appear in the top right of the images. They do not appear on the shop page. How do I get rid of them? I do have some code injection in the advanced-code injection and footer CSS areas, but I deleted all of it and the boxes still appear. Thanks!

Figured it out. Used the inspect in Chrome to figure out that it is a product status box (showing that it was sold out, because those are currently set to zero in quantity) 

So upping the quantity does it or changing the box color to white like this in design/custom CSS:

.sqs-block-summary-v2 .summary-product-status .product-mark {

    background: #fff;
