IPv6 not working on Eddie for Android

[User of AirVPN 47]

I am using the Eddie for Android latest version, and with the IPv6 setting set to "request", and when I connect to one of the IPv6 enabled servers such as Capricornus, I do not have IPv6 connectivity, only IPv4. ipleak.net only shows the VPN IPv4 address, and I am unable to view IPv6 only sites such as ipv6.google.com. how can I fix this and be able to use the VPN'S IPv6 address?
