I think it is not the issue of pgpoolAdmin,
because I tried the latest pgpoolAdmin, it works well.

Could you show the result of "show pool_nodes"?

  # psql -U postgres postgres -p 9999 -c "show pool_nodes"

Please try to edit "/etc/sysconfig/pgpool" and restart pgpool.

# vi /etc/sysconfig/pgpool 
(edit OPTS)
OPTS=" -D -n"

# systemctl restart pgpool
