traefik not working when a service is in multiple overlay networks - docker-swarm

Question

We can see that "portainer" is in both public and agent_network overlay networks. And it has two IP addresses, 10.0.38.7 and 10.0.39.7.
traefik is only in public network, it has IP address 10.0.38.6.
The problem is, from traefik web UI, it refers "portainer" as 10.0.39.7 instead of 10.0.38.7. So that it fails to work.
Any solution to this?
