Instructions fail on install/update step due to services "activiti-postgresql-headless" already exists error

[JimBarrows]

The error:
Error: release activiti failed, and has been uninstalled due to atomic being set: services "activiti-postgresql-headless" already exists helm.go:84: [debug] services "activiti-postgresql-headless" already exists release activiti failed, and has been uninstalled due to atomic being set
In the debug I see:
client.go:477: [debug] Starting delete for "activiti-postgresql-headless" Service client.go:481: [debug] Ignoring delete failure for "activiti-postgresql-headless" /v1, Kind=Service: services "activiti-postgresql-headless" not found client.go:477: [debug] Starting delete for "activiti-postgresql-headless" StatefulSet
So, the postgresql-headless both exists and doesn't exist. One of these is lying, and given the previous error I've reported I"m guessing it's the error message, and the debug log is telling the true.
