Keith, there's on flaw in your review.
Looking at the OP's summary, you can clearly see 4 meals - which agrees with the comment from NCL.
What's not shown (and should be) with the addons is the original FAS 3 meals.
I don't know if the Platinum meals are supposed to show with the addons or not, but they don't seem to be listed.
Lastly, the purchases shown are for Specialty Dining Upgrade X 2 plus another Specialty Dining Upgrade X 1 - which tallies to the 3 Specialty Dining package listed with addons. Of course, that means using the upgrade twice (apparently ordering for only 1 passenger on the second) which you think is not allowed.
Worst case scenario, the summary shows 5 meals each for 2 people; so, NCL saying I see you have only 4 is utter nonsense.
All in all, this is quite a mess.
