SONOFF ZB-01 Entities changed

Hi,
some days ago my wife told me the the garage-light is not switching any more…
I investigated, and saw that the SONOFF ZB01 hardware was functioning by the key,
Also HA did know the state of the on/off, so the zigbee was known by the network…
But switching the light from HA not possible.
I saw that the entity function/name to switch on/off the light had been chnaged, because
after a new interview of the device the “light” function was new…

Now it’s working but why did the names change in HA after an update ? Why ?
