IPFW FQ_PIE is not working in FreeBSD 13.1

ipfw pipe 1 config bw 10Mbits/s delay 20ms
ipfw sched 1 config pipe 1 type fq_pie
ipfw queue 1 config sched 1"
ipfw add 100 queue 1 ip from 172.16.0.0/16 to 172.16.0.0/16

I put these commands in my router which contains FreeBSD 13.1. My client and server is FreeBSD 13.1. I just used iperf3 to test it.

I tested it with FQ_Codel, Codel and PIE. It works properly. Only with FQ_PIE it does not work. What should I do?
