I have upgraded to Backdrop 1.27.0 and enabled the CKEditor5 on 7 sites
Then I changed the Editor in the Text Formats and disabled the CKEditor4 in the Modules List.
I then Uninstalled the CKEditor4 from the Control Panel.
I cannot find the CKEditor4 Module in the Modules Folder to delete. It is still showing as not enabled in the Modules List, but is no longer in the Uninstall List.
Have I missed something?
