Hi there!
Can you please reconfirm if you’re able to replicate this behavior on Storefront theme?
You might want to set up a staging site for testing if this cannot be done on the live site. This plugin lets you set up Staging sites (ensuring the live site stays intact during the testing process): https://www.ads-software.com/plugins/wp-staging/
If yes, and you’re still having trouble with this, Could you please share a copy of your site’s System Status? You can find it via WooCommerce > Status.
Select “Get system report” and then “Copy for support”.? Once you’ve done that, paste it here in your response.
