Encrypted phone, unlock screen by fingerprint is missing

I did flash my MotoG4+ yesterday night. So I am playing with setting now.
I did manage to setup unlock screen by fingerprint. So I have PIN and two fingers.

Then I decide to encrypt the phone. So after battery did fully charge I did encrypt phone.

After that I am not able to unlock screen by fingerprint. I also don’t see fingerprint configuration in Security menu.

Please, do I oversee something? or it is a bug?
thanks

well, I did restart phone today. And fingerprint configuration is back in security menu and also I can unlock phone by touching sensor.
