I created a html-file in Content-Administation > KM-Content > KM-Content and choose option "Edit online" for editing this file in the editors. At first I have choosen the "Text Editor" for editing; then I opened the "HTML editor" for editing. Now, I want to open the same file in the "Text Editor" via "Edit online" again. But the request which editor I want to use, does not appear any longer. The "HTML editor" will be opened automatically without I can make a choice. I tested it several times: Always when I use the "HTML-editor" for this first time for editing a file, then the request for editor-choice will not be opened anymore.
How, can I use the "Text Editor" again - What/Where I have to do, please?
