replace dummy sensor with real sensor

[Gravityz]

Hello,
i am trying to replace a dummy humidity sensor
with a real humidity sensor which is discovered by MQTT AD

however when selecting replace the new sensor does not show up.

i thought i replaced dummy sensors with real sensors before.

dummy type:Humidity subtype:Lacrosse TX3

mqtt ad sensor type:Humidity subtype:Lacrosse WX2300

Any idea why only last year from history is moved? All other years are gone.
