Hey Orlando,
I made further investigation of your site and it seems that the WooCommerce X integration was being replaced by WooCommerce. I have tried as many times as I can to replicate the issue in my local testing server. I updated my WooCommerce with X 5.2.5 and no issues for me. I am guessing that maybe, there are theme files missing in your site. I’d like you to re install theme. If you could give us ftp details, then maybe we can investigate further because all of your issue is not happening in our test sites.
Please let us know what you think and provide us the access if you permit us to re install the theme.
Thank you in advance.

So, woocommerce released an update yesterday, which outdated a couple of core php files (product-images and product-thumbnails). I updated the x-child files and thought it might’ve fixed my initial problem, but I honestly can’t tell. I notice that when going from one shop page to another there’s a flash or moment when the images appear large again, as if there was no global js fix, but then the code kicks in and corrects (resizes) the images. Not pretty at all.
