New MI10 VoLTE unknown number

[bkk232]

Hello.

I have a problem with my phone mi10. I have disabled provider checking and got VoLTE working on my phone. But when i recive a call i always get unknown number? If i disable VoLTE number is normally shown. Outgoing call are working normally. Previously i had mi9t and incomming call on VoLTE showed normally.

Can i fix this?

I often need to switch
Call settings - advanced settings - caller ID
back to shown.
I don't know why it often turns off again by itself
