Discovery of deleted nodes

I am currently running OpenNMS 16.0. I want to move to 21.0.5. I am simply doing a new install of 21.0.5 on a separate server and rediscovering network devices. The new server is Centos 7.4. Discovery and SNMP are working on the 21.0.5 server. But I am having trouble rediscovering a node that I have deleted. I am unable to find a discussion of this behavior through web searches - which makes me think that I have done something wrong. Discovery is set to look for a range of 3 IP addresses. Discovery initial delay is 30 seconds, and rediscovery is 60 seconds. log4j2 is set to debug level for discovery. To test this, I delete the node and then confirm it is deleted by verifying that its corresponding rows are deleted in the node and ipinterface tables of the opennms database. Once verified, I begin watching the discovery.log file. I see Discovery begin its operation every 60 seconds. It pings only the undiscovered IP address. It doesn't attempt to ping the two previously discovered addresses (including the address of the node I have deleted). The only way I can get the deleted node to be rediscovered is to restart OpenNMS. Even restarting the discovery process doesn't help. Does this seem right? What am I missing? Or what have I done?
