Check_mk api effective_attributes=1

Hi,

when I get host detail webapi.py?action=get_host with effective_attributes=1 it’s seem not working (Checkmk 1.6.0p9 raw).
Example: if I set folder site in json result there isn’t site value. If I set this value directly in host wato then value appears.

Thanks for your hard work.
Vittore.
