Version V16 - In Education Workspace - Doctypes appearing 2 times - doubled / duplicated - Had already cleared cache and run bench migrate and bench build but still not fixed , is there any other way to fix this ?

Try one thing,

  1. Go to Desktop Layout

  2. Delete layouts

  3. Bench Migrate and Rebuild

there are no layouts created to delete , desktop layout is empty as shown below ,
