Hi there!
I have tried to replicate the issue on your site, and I can see variation switch is not working properly. It looks like you are using a third-party plugin to display variation switches with image icons.
To assist you better with testing, could you please deactivate the plugin you are using for variations? I want to confirm whether the issue is caused by the variation plugin or not.
If you still face the same issue, could you please deactivate all plugins except WooCommerce and see if that resolves the issue?
If that does not help, I’d like to understand your site better. Please share the necessary information below so we can investigate the issue further:
- System Status Report?which you can find via WooCommerce > Status
- Fatal error logs?(if any) under WooCommerce > Status > Logs.
Please use https://pastebin.com/ or https://gist.github.com/ and share a link to that paste in reply here. Once we have more information, we’ll be able to assist you further
