CSR generated during SNO dualstack cluster restore contains unexpected IPv6 address

After restarting kubelet as part of 'restore to previous cluster state' procedure a CSR is created. Inspecting it reveals that IPv6 address is incorrect:

oc describe csr csr-tmrn2

Note "fd69::2" IPv6 address. Previously generated CSRs report expected IP

So far ran the procedure once

1. Follow "Restore to previous cluster state" procedure on baremetal dualstack SNO cluster
2.
3.

Rogue IPv6 address present in CSR

Correct(IPv6 address configured by operator) is added into CSR

That's interface from SNO node:

 ip a s br-ex
10: br-ex: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN group default qlen 1000
    link/ether 40:a6:b7:9a:6a:e8 brd ff:ff:ff:ff:ff:ff
    inet 10.1.101.49/28 brd 10.1.101.63 scope global noprefixroute br-ex
       valid_lft forever preferred_lft forever
    inet 169.254.169.2/29 brd 169.254.169.7 scope global br-ex
       valid_lft forever preferred_lft forever
    inet6 fd69::2/125 scope global nodad
       valid_lft forever preferred_lft forever
    inet6 2620:52:0:165::31/124 scope global noprefixroute
       valid_lft forever preferred_lft forever
    inet6 fe80::42a6:b7ff:fe9a:6ae8/64 scope link noprefixroute
       valid_lft forever preferred_lft forever


After some time those CSRs were automatically approved
