MailPoet error with “client note” WooCommerce mail

Hello,

I’m using MailPoet to design my WooCommerce mails.

The problem is that, I changed the title and body message for “Client Note” mails in WooCommerce. The title changed in MailPoet mail design, but not the body message.

I tried the following:
* Change again the Client Note body.
* Deactivate and Reactivate the Client Note mail in WooCommerce.
* Clear Cache and Cookies.

Ho can I solve it?

Thank you for your support.
