New Exchange 2010 Mailbox Store not available for selection in ADManager

New Exchange 2010 Mailbox Store not available for selection in ADManager

I have a new installation of ADManager Plus and I'm working on creating templates for our helpdesk to use for account creation.  After I installed ADManager, I found the need to create an additional Mailbox Store which will be used specifically for account creation.  However, this store is not available in ADManager Plus.  Is there anything I need to do in ADManager to make this Mailbox store available? 

I'm able to manually assign this Mailbox store in the EMC without issue.  I've migrated a couple of mailboxes to it just to test it out as well.  All seems to be working fine, it's just not available for selection in the single user creation wizard.

Thoughts?  Thanks.
