Hi,

1. Actually, our theme has out of stock label on shop page. Could you please provide us your admin and FTP access so we can check why it doesn’t work for you?

2. Probably you have disabled reviews for some products https://www.templatemonster.com/help/woocommerce-how-to-enabledisable-reviews-remove-reviews-tab.html

3. Most likely you used some kind of import plugin that doesn’t work correctly and set images sizes to 1×1. Try to add the following code snippet to the Custom CSS area in Theme Settings to fix this

.product-element-top img {
    width: 100%;
}

Regards
