I get my IPv6 addresses from ISP by prefix, then I config local LAN with SLAAC.
With Add Default Route enabled, I will get two routes auto configured.
1st
2nd
I have to delete first route manually to get IPv6 work.
What could cause this? How can I fix it?

You uncheck add default route.
If I uncheck add default route, it seems that the second route won’t add automatically either.
You should have “add default route” in the PPPoE client interface and NOT in the DHCPv6 client.
Then it will work OK, maybe after a disable/enable of the PPPoE.
I tried your suggestion.
The result is that the first route will be added automatically, the second route is gone.
And then it works. Case closed.
