Discovered Elements

Hello everyone
Clouster currently have a 6-AP and 2 BH, with prizm 3.0 but I can not see some of my AP I can only see three with their respective SM. in the tab discovered Elements high AP I want, but do not give high, I ping and all arrived.
¿Are there any parameters to be activated in my AP or I can verify within the Prizm?.
Let me already that I could put up to 3 AP if any problem.
You commented that acquired the prizm 3.0 with 10 licenses

P.D I have Windows XP and DBpostgre already working.
