Solved: IPv6 stopped working on LAN, WAN is working

Ok i put the wan6 back into my interface config and restarted the router, heres how the config looks now:

root@turris:~# cat /etc/config/network 

config interface 'loopback'
	option proto 'static'
	option ipaddr '127.0.0.1'
	option netmask '255.0.0.0'
	option device 'lo'

config globals 'globals'
	option ula_prefix 'fd1b:24d2:ca62::/48'

config interface 'lan'
	option _orig_ifname 'eth0 eth2'
	option _orig_bridge 'true'
	option _turris_mode 'managed'
	option proto 'static'
	option ipaddr '192.168.1.1'
	option netmask '255.255.255.0'
	option ip6assign '64'
	option device 'br-lan'

config interface 'wan'
	option username 'xxxxxxxxxxxxxxxxxxxxxxx@t-online.de'
	option proto 'pppoe'
	option password 'xxxxx'
	option device 'eth2.7'
#	option ipv6 '1'
	option ipv6 'auto'

config interface 'vpn'
	option _orig_ifname 'tun0'
	option _orig_bridge 'false'
	option proto 'none'
	option auto '1'
	option device 'tun0'

config device 'br_lan'
	option name 'br-lan'
	option igmp_snooping '1'
	list ports 'lan0'
	list ports 'lan1'
	list ports 'lan2'
	list ports 'lan3'
	list ports 'lan4'
	list ports 'tun0'
	option type 'bridge'

config interface 'wan6'
	option device '@wan'
	option proto 'dhcpv6'
	option reqprefix 'auto'
	option reqaddress 'try'

config device 'dev_wan'
	option name 'eth2.7'
	option igmpversion '2'

I do get shown two Interfaces WAN_6 and WAN6 which doesn’t look right for me:

Reconnected the client also nothing seems to have changed:
