BIND / Cluster slave servers does not support ipv6

OS type and version Debian Linux 11
Webmin version 1.998

Within BIND DNS Server, in the configuration section “Cluster slave servers” I add the ipv4 master, but I want to add an additional ip but the ip address turns out to be IPV6, and it turns out that it doesn’t work, I add the ip address but when I create the master zone within the slave only the registered ipv4 remains!

Any solution?
