Hi @tiagojoliveira ,
I inspected your site and saw the swapping effects were still activated. Somehow, the effects did not work properly. It just changed the images: https://app.screencast.com/EST8pBRuxZSAO
Please make sure you have cleared the caches properly from your site and browser before checking again in an Incognito tab.
You can also deactivate all other plugins, except WooCommerce and ours to check if they work again. Then reactivate others one by one to find which is interfering with our plugin.
Best regards.
