Dashboard problems?

I have upgraded Opmanager from 5.6 to 6 and now OpMan is 6003. After upgrade, I start discovery some devices in my network and found that Dash board cannot display "Routers with high CPU Utilization" table, only some table show
1. "Recent Alarms"
2. "Router Interfaces with high Rx Traffic - Last 24 hour(s)"
3."Router Interfaces with high Tx Traffic - Last 24 hour(s)",
4. "Routers with high Memory Utilization - Last 24 hour(s)",
5. "Servers with high CPU Utilization - Last 24 hour(s)",
6. "Servers with high Memory Utilization - Last 24 hour(s)" and
7. "Applications with high Response Times - Last 24 hour(s)"
only and a blenk at the "Routers with high CPU Utilization - Last 24 hour(s)"
Pls guide me what to do to show the ""Routers with high CPU Utilization - Last 24 hour(s)"?
Thanks.
