Variation images not showing

Hello,

My variations only show the main image for the product, not the variation image.
I’ve read the other posts in this forum about the same issue. And I’ve seen the solution is to use the “Main Image” for the image link, which is the default setting. This is how I have it set up. I’ve also tried other settings and went back to this. I’ve cleared my cache several times, yet the main image will only show, even though there is a variation image in place. How can I fix this so it shows the variation and not the main image?
Thanks
