DHCPv6 client doesn't create pool

Packages version 6.42.1 (same on 6.43rc6)
My ISP enabled ipv6.
Steps to reproduce the problem:
Open ipv6->dhcp client->add
Ask to receive prefix, set the pool name (pool1)
open ipv6-addresses->add
Assign pool1 to my lan bridge
Everything works fine.
Reboot mikrotik
Check ipv6-dhcp client
The prefix is acquired
Check ipv6-addresses
pool not found: pool1

How to fix that?

Were you able to fix that? I was thinking on a script to delay/restart the DHCPv6 client after reboot, hoping that will fix it.
