Ds4 profiles

Hi, Recently purchased a DS4, all is well except I have set up 2 profiles on the system for both drivers but it seems I have to manually select which driver I want when I start the car. I just assumed that whenever I got in, the car would select the profile associated with the connected phone.
Am I doing something wrong or is this not a feature, If not it should be, My last vehicle auto selected the drivers profile for the connected phone.
