Door knob door: Unlock also opens door without HomeKit


I have a strange issue which is similar to this topic: Make HomeKit/Nuki mapping selectable to enable users to trigger the “Unlock” command to the Nuki Smart Lock 2.0 instead of triggering the “Open Door” command possibly.

My door is one with a bar outside therefore I selected this option in the app. If I use the Nuki app (not HomeKit!) the doors get unlocked and opened because the latch is pulled back. Is this intended? Reading the forum and docu this behavior should only apply when using HomeKit right?

As a workaround I set “Choose door fitting” to “Lever”. Now “Unlock” only unlocks the door without pulling back the latch and “Open door” unlocks and opens my door.
