Zabbix Not Discovering previously Discovered hosts now deleted

[kionysus]

I have a discovery rule that says scan an address range and add the host and add the host to a 'Discovered Hosts' group. It found 97. I then deleted all 97 hosts; however, Discovery isn't finding the hosts again. Monitoring -> Discovery still shows all 97 hosts with uptime even though they were deleted from Configuration -> Hosts. How do I flush them entirely out of the DB so Device [Discovered] will actually grab them again and run the discovery action?

I have solved the given problem so: has renamed a detection rule.
