3560 sdm prefer dual-ipv4-and-ipv6 default

It seems I am not able to save the configs for sdm prefer dual-ipv4-and-ipv6
default.

I am doing an ipv6 lab.

I'm on a 3560 switch.

I do this command....

SW1(config)#sdm prefer dual-ipv4-and-ipv6 default

and then I save configs and reload the switch so I can now configure ipv6
unicast-routing and put ipv6 addresses onto the interfaces.

Everything is working good and then it comes time to quit for the day. So I
write the configs and save the configs to flash drive. Then I write erase and
reload to clean up the switch for the next guy in line.

Then i come back the next day to start again.

I load the saved configs from flash drive and do show sdm prefer and i'm back
to default template and all of my ipv6 addresses have been wiped out.

SW1#show sdm prefer
 The current template is "desktop default" template.
 The selected template optimizes the resources in
 the switch to support this level of features for
 8 routed interfaces and 1024 VLANs.
  number of unicast mac addresses: 6K
  number of IPv4 IGMP groups + multicast routes: 1K
  number of IPv4 unicast routes: 8K
    number of directly-connected IPv4 hosts: 6K
    number of indirect IPv4 routes: 2K
  number of IPv4 policy based routing aces: 0
  number of IPv4/MAC qos aces: 0.5K
  number of IPv4/MAC security aces: 1K

Maybe I will need save all of my ipv6 address configs on a notepad and just
expect them to be wiped out because this sdm prefer?
