Ok I just figured it out. I cloned the report to edit it. The Filter by Name is not what we would think. It is for OS Name as seen here..
and comp.[OS Name] like @Name
so I just ran the report and put windows% in there and yes my machine shows up. When I had R% I got nothing as our machine name starts with an R.
Anyway you can search or filter out in the upper right where it says Search.
Hope that helps.
