What makes an online store inspire trust? [Research]

I'm working on a research paper for a company that offers customer service plugins for Shopify/WooCommerce/Wix stores.

I've compiled a list of screenshots from various stores and altered some of them. About 50% of the examples are OK but, with the rest, something fishy is going on. I'm curious if you can spot what's out of order.

Can you spot what's wrong with this e-commerce website?

I hope the survey is not too difficult?
