OEM 12c agent - target name for oracle_home incorrect

Question

We have a question re: the OEM agent.
Why would the target name for oracle_home be different than the hostname that the agent is running on?
In this case, the agent target name is sometimes the same as the hostname, as this:
-9 n/a oracle_home agent12c1_2_cbdn-000-002-001-018
hostname = cbdn-000-002-001-018
but we also see this:
-9 n/a oracle_home agent12c1_2_cbdn-000-00-2-002-018
but hostname is cbdn-000-002-002-018
-bash-3.2$ emcli get_targets -target=oracle_home

Thanks for the help.

Please see the following doc for instructions on deinstalling an EM 12c agent. An EM 12c agent has its own Oracle home, so uninstalling it will not affect other Oracle products on the host.
