Automation switch is off, but Motion switch active

[SCoe2k]

I have the below setup:
{
"type": "automation",
"name": "A-Kühl-Gefrier",
"period": 60,
"autoOff": false
}

If one fridge door opens, the switch is set to on.
After 1 min the motion detection is active. In that case I check, if door is still open:

• yes: message to me
• no: turn off switch

That works fine. Nevertheless after I have turned of the switch, the motion switch is active every Minute. How can I really deactivate. What is going wrong?.
Usually the motion detection should be off, if the switch itself is off, isn‘t it.
