Activities still showing in Home.app after removal from Harmony
Activities that previously existed but have been deleted in the Harmony app and thus from the hub are still showing in HomeKit. This may or may not be a problem with homebridge-harmony directly. 

I have of course restarted home bridge, rebooted the server (Pi), upgraded both Homebridge and this plugin.

Looking for a troubleshooting path to follow. I am unable to find any config settings related to this. Please advise.
