During the initial setup the Smart Lock calibrates itself and adapts to your door. If your door is for example designed to be locked twice, then the Smart Lock will also lock it twice.
To re-calibrate your Smart Lock later, tap on the desired Smart Lock in the Nuki app and enter the lock settings. Then go to "Manage Smart Lock". Here you can find the option "Calibrate Smart Lock" to initiate a new calibration.
