[Samba] Samba generating wrong ipv6 and ipv4 address

[Patrik]

My config is this:
# Global parameters
[global]
# bind interfaces only = Yes
# if this is turned on, always perfect
# interfaces = lo 192.168.78.20 2001:470:1f1b:5b3:21b:21ff:fea6:ce93
# interfaces = lo 192.168.78.20 2001:470:1f1b:5b3:21b:21ff:fea6:ce93
192.168.81.20 2001:470:1f1b:5b5:21b:21ff:fea6:ce92
#        interfaces = lo 192.168.81.20 2001:470:1f1b:5b5:21b:21ff:fea6:ce92
# if all interfaces known, order is important, the last is the required
# interfaces = lo 192.168.78.20 192.168.81.20
# interfaces = lo enp1s0f3  enp1s0f2
