If someone can provide a savegame with exact recreate instructions where both options 1 and 2 do not work, we'll be happy to look at it.
I have a save from the Steam version where pressing '2' gives 100000 health to only one of my squad mates, and pressing '1' gives 100000 health to the other. Shepherd stays at his original health. (I'm guessing this is an "off by 1" bug?)
This has happened to me on both V1 and V2 trainers.
PWizard PM me on how to send the save to you.
