mroute: "ip mroute show" not working when "to" and/or "from" is given

The command "ip mroute show" is not showing routes when "to" and/or "from"
filter is applied.

root@mazhar:~# ip mroute show
(10.202.30.101, 235.1.2.3)       Iif: eth0       Oifs: eth1

But When I applied filter, it does not show anything.

root@mazhar:~# ip mroute show 235.1.2.3 from 10.202.30.101
root@mazhar:~#
