How the abolit of Amy works?

Medic: During each End Phase, for free, the Survivor and all other Survivors in the same Zone may heal 1 Wound. The Medic Survivor gains 1AP for each Wound healed this way.

I don't understand how to activate.
I had a situation where, at the end of my turn, I was on the same space as Wanda, who had 2/3 health, and she wasn't healed.

This ability is unlocked in the red level of adrenaline, so you don't have that at the beginning of the game

When you will have it, really have it, that description on back of characters cards is totally wrong and confusing, button will appear on top panel to heal all that can be healed.

PS: Many survivors on back has wrong information. I have no idea where those came from or what for those are used. Maybe some previous version of game, or rules.
