Gear Engage Delay

(UK) I have had a First Edition E-Pace for 11 months now, which will have a service in a week or so, having only done 2,200 miles so far. It is a great car and can be a beast if I hit the accelerator pedal. However, it has one major fault that indeed is dangerous and a real pain, in that if parked on an incline, reverse gear does not immediately engage, resulting in the car rolling down the incline once I take my foot of the break to move it to the accelerator. As a consequence I dare not park on sloping ground without a safe space in front. I am hoping that this can be sorted when the car is serviced. Has anyone else had this problem.
