Products on Google Images showing Wrong Images

I'm having some trouble with how my product images appear on Google Images. From the screenshot attached, you can see that the pages it links to are not related to the images displaying (for example, you can see a page link to a Dragon product when it shows an image of a Bunny product). I think the problem is that it's taking images from the "related products" section, and using those images instead of the product images.

How can I make it so that the displayed images and page links are correlated? Should I just remove the "related products" section? I've emailed Squarespace for help but they only send replies with general SEO tips.
