Demystify OBC ID codes in HAL Profile

[daybrake]

We are new to HAL and are working on getting approved for various OBC (i.e. AARP, military, teacher).  I now see 3 different OBC ID codes in my Mariner profile.  Two have the same "sail by" date (12/30/2025) and have an OBC of $100 each and one has a sail by date of 8/10/2027 for $50.  How can I tell which code is for which OBC offer?

Military and teacher are $100 each. AARP will initially show as $50 until used. Its value depends on length of cruise and cabin booked.

The one with the 2027 deadline is AARP OBC I believe.

Now, when we log onto our Mariner account all of the approved OBC (AARP, Military, Teacher) are now missing from our account profile.  They had not expired yet and we haven't booked a cruise yet to use these.  When we tried to re-apply for the Military OBC, we received a message that we had already used that benefit?  How should we proceed about getting these OBC to show up back in our Mariner account profile again?

The HAL website is notoriously awful. Try again another day and it will be back. I've had entire bookings disappear one day and then reappear the next.
