EQE – Snow in the trunk

Hello community, I had opened the tailgate with my new EQE today, despite some snow on the car. This led to the whole snow of the window in the back and the boot lid in the trunk. Now all my cars had felt a lip or similar in front of it to prevent this happening. Is there something missing in my EQE or is that normal? I didn’t read the operating instructions exactly after that, but the car must be completely off the snow. to open it? OK, that was ironic now. Thank you and say hi Marc
