Here is a couple of document issues:

• Document dropdown menu - Version 6
  -- References https://getdatepicker.com/docs/6/ should point to https://getdatepicker.com/6/
  

• Functions: Display https://getdatepicker.com/6/functions/display.html
  -- The On this page list (right side) has incorrect items (These items belong to the Functions::Overview section)
