No IPV6 menu on Routerboard 951G-2HnD

Hi

I have a routerboard 951G-2HnD, and I want to configure IPV6. However there is no IPV6 menu in WInbox as you can see on the screenshot. In the terminal only /ipv6 export command is available

How can I solve this?

Thanks!

Make sure the IPv6 package is installed and enabled.
