Ghost messages send by the Telegram node

I have a flow where I monitor the ONLINE status of a device, I would like to be informed of the occasion that the thermostat is OFFLINE and act upon that status in another flow

NR receives a JSON from the google API, the response is set to a Global context value:

With the result in the context view:

Looks ok?

Then that value is injected every 5 minutes to another flow, to act on the status:

I've set a RBE after the inject, because I only want to receive a msg when the status has changed.

Living status debug:
{"living":{"status":"ONLINE"}}

So far so good, thermostat is ONLINE (checked that in the global context) both debug living status and living status RBE give the expected result: every 5 min a message in the debug living status, and nothing in the living status RBE.

Then the evaluation of the msg.payload.living.status that has been injected:

msg.payload.content of the 3 change nodes on port 1,2,3 is online, offline and otherwise.

After deploy, I get an ONLINE message, that's good.

Injecting numerous times, no message. Looks like RBE is working ok.

But after some minutes and then every 5 minutes, an OFFLINE message is received, the message does not leave a trace in the RBE debug node, nor in the offline debug node.

I am puzzled...
