Just started noticing it today (I don't do anything with the info - just use it to see past cheerlight tweets)
I could switch off and on again to see if it clears but I'm wondering if I can use new debugger to see what might be going on
FTAOD - my logger subflow (which sends to retained timestamped topic on my local MQTT broker) also shows the duplicates so I don't think its an issue with the debug node
