Nuki 4 pro Matter Unlatch is not working?

Hello everyone,

i tried to connect a Nuki 4.0pro via Matter to Home Assistant (i use the Apple Thread Network, but connect the Nuki directly to Home Assistant).

I have installed the latest Firmware (4.2.6) and also HA is up to date. Since 4.2.6 Nuki supports the unlatch action, but unfortunately i can`t seh the unlatch button in the lock entity…

My other Nuki 4.0pro, connected via MQTT, shows the unlatch action.

What is wrong here?
