We are trying to edit the mailing templates for password reset and others using Technical>Email>Templates view in Developer mode. I can click edit and edit certain changes in the tabs. However, any changes I make to the email in code view or in the WYSIWYG editor are removed when I click save. I can change things as much or as little as I want, but save just reverts it back to the default. I've tried duplicating and editing a copy but has the same result. Hoping to change the wording and coloring to match our company better and cannot.
