Values not saved when using MQTT

Hi, I am using the MQTT template to subscribe to MQTT values, but when I query for property history I only get the values which I set manually. I think it's a permission problem. Any help is appreciated. Thank you!

Do you have the 'DataChange' for the MQTT mapped property set to Always?

(Besides that, is it logged)

Yes, it's set to Always. I set also Persist and Log.

Not too sure then what the issue might be, as an alternative you can log it from a subscription to the datachange?
