The Cheyenne Wyoming navaid cys is not in the database. KCYS is.
The CYS VOR is in the database and we are investigating why it is unable to be added to the Route using the Route Ident search box. We believe that it is due to a maximum result limit in the search and since "CYS" is used quite often in Canadian airport identifiers, that may be causing it to not show up in the list due to too many results.
That is just a theory at this point but we are looking into it further.
Until fixed, you can manually drag the route line to the CYS VOR and it will be added to the Route.
