Transmission ipv6 problem

[netspy2]

Hello!

I have Asus RT-AC68U router with firmware 376.48_1. I setup transmission with this manual. When i run start script then launched four process of transmission-daemon. And in log present string "Couldn't bind port xxxxx on ::: Address already in use (Is another copy of Transmission already running?)". IPv4 fine.
On Asus RT-N66U with entware all right, launched one process.
Also with the daemon aiccu, four same process. But it working.
Any ideas?
Sorry if double. And sorry for my english.
