Hello Clavicus,
What your are seeing are authorizations. When the order was generated one was opened for the amount of the order at the time. When the warehouse printed the pick list for the order the authorization had already expired (it should disappear from your account as soon as your bank releases the hold) so a new one was opened, but only for the amount of the set of dice that was added to the order after it was generated. That authorization will finalize for the full amount of the order when it ships. I don't see any issues with the order.
