Preffered SIM card auto change

[kiimDK]

Samsung Flip 3. I have one physical sim card (sim1) and one ESim. ESim is prefered to SMS, Calls and data. Every time I restarts the phone it change prefered sim card to the physical sim1 to SMS, Calls and data. The phone have newest firmware. Any idea what could be wrong with the phone?

In Sim Card Manager E-sim is prefered. But when phone is restarted it change prefered to SIM-1. Then I have to change back to E-sim.

My preferred sim is E-sim. Until I reboot phone, then preferred sim is physical sim instead of E-sim. And I must change it back to E-SIM.
