Email template gets delteted

Hi,

I’m sorry for this delay in reply. Thank you for kindly waiting.
Do you still have your staging site?
If yes, please remove the data again.
To ensure, you can export the template, after you finish removing your website, you can import the templates back to your production site. https://prnt.sc/CcKoSHBrMksA

Best regards.

I have export and try to import data but import is also not working in your plugin. this is useless plugin.

Have you tested for conflicts? I would recommend running through the following troubleshooting steps if not: https://docs.woocommerce.com/document/woocommerce-self-service-guide/
