Problem allocating service packages to users via delegated admin

I've created a custom service package using the sample templates. Upon assigning this newly created package to a user via Delegated Administrator I receive the following message "cannot create user - all service packages of this type have been allocated". Problem is I've made about 200 available and the stats for this package show 0 used. Please advice.

Cheers
