The emails sent are no longer those generated by Decorator

Hello,
I installed your plugin several weeks ago on a new site and everything was working fine.
But since yesterday, when I test sales, it’s the basic woocommerce email that is sent… not the one generated by your plugin.
I specify that this site is under construction, and that I do a lot of tests and manipulations on it… so I may have made a mistake, but I can’t find (customized emails are generated and saved with Decorator and if I test sending emails directly, it’s good…).
I uninstalled and reinstalled the plugin, but with no more success.
I can grant you access to my admin if you wish.
Thanks for your help.
