Steps to reproduce:

Host Status Widget:

Hostgroup shows 1 average warning, I drill down to a host that it indicates it has the issue, Host shows up in host status dashboard widget - 1 average warning

I click on the hostname, and it brings me to another screen "Problems"

nothing shows up as far as a problem.  

System Status Widget: doesn't show any issues for that hostgroup. 

How do I clear this up? 

I've attached screenshots.
