Potentially they had the seven powers but only 6 shifters so one had 2. Maybe they lost that one the powers were split one was recovered and the other was not perhaps they converted to do something similar like Eren Kruger was it. They could also just be saying they have the powers so there's no loss of moral for the troops at the loss of 2 powers already being the female and colossal titan.
