Weird behavior Locking system

Hello everybody, have you noticed that you can get into your van even though the car is actually closed? I have an XC60 MJ2012 with electric boot flap. Close the car with the remote control, open the trunk with the FB, close the trunk again. The car looks closed (mirror opened, buttons in the doors are below). The doors cannot be opened, but the boot flap can be opened with the handle. I would have expected the rear flap to close automatically after the closing. – funny logic from VOLVO. Greeting Hans-Dieter. P.S. that works exactly like this for the V70.
