DHCP Server does not send Framed-IP-Address in RADIUS Access-Request if ciaddr = 0.0.0.0 , but yiaddr assigment is correct

If

12:15:31 dhcp,debug,packet 2004-1001 received request with id 1776182345 from 0.0.0.0 
12:15:31 dhcp,debug,packet     ciaddr = 0.0.0.0

Client IP address is assigned by Mikrotik DHCP Server and expected behavior is sending yiaddr in Framed-IP-Address.
