This is vC Ops Manager 5.7.0 Hot Fix 1. If you don't have historical data you want to preserve I would recommend to deploy a new VCOps 5.7.1: http://communities.vmware.com/thread/448864
If you want to debug this further you can upload the diagnostics bundle in order to have a look. If Risk and Efficiency are affected this is because of some problem in the capacity engine - I suspect you don't see the subbadges under Risk and Efficiency also, right?
Thanks,
