capsman ipv6 not work well

I have been using the capsman function for a long time without any major problems. But recently, I use IPV6 to connect to capsman, but it does not work well. The wireless client can connect to the wireless network, can use DHCP to obtain the IP address, can PING the gateway, but the TCP protocol can hardly work. Later, I found that there was nothing wrong with the smaller packets, and the larger packets could not pass through, were partially discarded without any information, and even caused the Capsman router to operate abnormally.
The same configuration, I use layer2 or ipv4 address to connect to capsman, it works normally, but only change the address to IPV6, there will be problems.
IPV4 addresses are about to run out, and IPv6 functions should be strengthened. Hope to solve the IPV6 support of capsman sooner! !

Thanks!!

When I use the network interface directly, the wireless work is normal.

/interface wireless cap
# 
set discovery-interfaces=bridge1 enabled=yes interfaces=wlan1

When I use the IPV4 address to connect, the wireless work is normal.

/interface wireless cap
# 
set caps-man-addresses=192.168.58.1 enabled=yes interfaces=wlan1

When I use the IPV6 address to connect, it just seems to be working. The wireless CAP can connect to the capsman, and the wireless client can connect, but the network is not working properly. It can be pinged and a dynamic IP address can be obtained, but no website can be accessed.

I think this is just a BUG, and hope to fix it in the version update.

/interface wireless cap
# 
set caps-man-addresses=2409:8a44:3051:ecc:4e5e:cff:fef0:1ca4 enabled=yes interfaces=wlan1
