Required to issue "Remove User Code" twice

[firstof9]

When utilizing the "Remove User Code" command you have to trigger it twice in order for it to actually work.

{
    "Label": "Remove User Code",
    "Value": 0,
    "Units": "",
    "ValueSet": false,
    "ValuePolled": false,
    "ChangeVerified": false,
    "Min": -32768,
    "Max": 32767,
    "Type": "Short",
    "Instance": 1,
    "CommandClass": "COMMAND_CLASS_USER_CODE",
    "Index": 256,
    "Node": 14,
    "Genre": "System",
    "Help": "Remove A UserCode at the Specified Index",
    "ValueIDKey": 72057594287013910,
    "ReadOnly": false,
    "WriteOnly": true,
    "Event": "valueAdded",
    "TimeStamp": 1593804665
}

topic: OpenZWave/1/command/setvalue/ payload:

{
     "ValueIDKey": 72057594287013910,
     "Value": 3
}

Results:

{
    "status": "ok",
    "TimeStamp": 1593833969
}

The value persists and doesn't actually get deleted until you issue the same command a second time. At which point the Alarm Type changes to 33, and the Alarm Value changes to 3 (code slot).
