It looks like https://vyos.dev/T6972 introduced a bug that makes it so you cannot commit interface changes when an interface has a dynamic IPv6 address and the user is trying to remove it from being a DHCP client

The comment above the code specifically is
# We will force removal of any dynamic IPv4 address from the interface
So it may also have been meant to only deal with IPv4 addresses, but since it's not looking at specifically inet addresses, eg address_info['family'] it is also looking at IPv6 addresses
