Cancelling refreshment packages for 2 of 4 people - can it be done online?

[MaryCS62]

So, several months ago, when we booked our upcoming Aug cruise, DH & I were not going to get the deluxe package because we were supposed to be Diamond after our January Anthem cruise -- (11 nights, Jr Suite (2 pts/night) + the promotional double points for booking within certain parameters), so we booked refreshment packages for 4 of us - 2 DD's in 1 room, DH & I in the other. 

Unfortunately, stupid positive Covid test for one of our party meant we had to cancel the January cruise, which meant no Diamond status at this time.  In the intervening time, I decided, due to health reasons, that I was going to severely limit my alcohol & high carb intake, but didn't want to fuss with calling for 1 DBP & 1 refreshment for me & the same for the DD's in the other room (one cannot drink, again, health reasons).   So we switched so that DD & I are in one room, DH & other DD in the other so that they could order DBP.  DH did it last night, but didn't realize that doing that did not automatically cancel the previously ordered refreshment packages that are still listed for the 2 of them.  

I went to cancel, but am afraid if I do, I will have to cancel all four, as there does not seem to be an option to just cancel two. I don't want to do that, because we got them at a much cheaper price than they are currently on sale for.  Am I stuck calling Royal anyway to do this??
