Resyncing phone contacts every time in the car

[KACW]

Hello. Does anyone know the point of the car phone settings in the MG ZS EV 2022 when you have saved your mobile phone contacts as local contacts? See photos attached. I tried calling from those contacts to make a call when my phone is in the car. I was attempting this as each time I get into the car I have to sync my iPhone contacts. I would think my phone is recognized when Bluetooth is on and my phone connected, though each time the car is turned off and back on again I must resync contacts. It’s as if there is no memory being retained between the car and the phone. Also I have to note the signal part of my car doesn’t seem to activate, and wondering if no signal is why I have to resync each time.
Thanks for any help that is offered.
