This happens with every automatic transmission if the vehicle is parked incorrectly. In the photo you can see how the parking position of the automatic transmission prevents the vehicle from rolling away.
The correct way to park a vehicle in an incline is to stop in D or R, stay on the brake, activate the parking brake, slowly take your foot off the brake and only then set the automatic transmission to the P position. This way, the entire weight of the vehicle is not on the pawl (#10 in the Picture). To drive away again, stand on the foot brake, switch the automatic from P to D or R and only then release the parking brake.
This way, your automatic transmission will remain undamaged for a long time
