Hey, sorry for the late reply.
I have saved the perma links again to no avail.

When i go into the Settings to edit any kinds of email, this designer shows up. There is no “button” in the top right to choose templates.
When i try to edit one mail at a time and not the “whole” template, a designer shows up but no chance to choose templates.
This shows up when i go into the woocommerce tab:
“Deine installierten WooCommerce addons haben die e-mails die unten angeführt sind registriert. Diese e-mails k?nnen nicht mit unserem mailbuilder bearbeitet werden aber du kannst globale Einstellungen hinzufügen.”
Where there is literally only Woocommerce & German Market installed that could in someway interfere with the Email and their Templates.
