one translation correct or both

Haben sie alle zehn Geräte? when I translate do you all have ten devices? I get it wrong and should be do they all have ten devices? When I have to choose the right translation from a choice of three, do they all have ten devices is not the only answer, both are correct. I find this difficult to understand, it is contradictory

The capital letters are important here: Sie (with capital) means you (formal), sie (no cap) means they.
