Mqtt-in repeated messages bug?

General

When I switch from a parsed JSON object to auto-detect I get 2 messages:

livingroom/fan/uptime : msg : Object
object
topic: "livingroom/fan/uptime"
payload: 3493
qos: 0
retain: false
_msgid: "5d655259.c8ae2c"

1x Payload as number
1x Payload as string.

I strongly suspect this is node-red.
