S21 showing private calls only

[BusiJ]

Good day

I am using S21 FE and all incoming calls reflect as private. I have tried everything in the settings. 

Sim 2 works perfectly, my main number in Sim 1 is the one giving me issues. 

Your assistance will be appreciated.

Thank you. I did, it's sorted.
