They apparently used a chassis lift, rather than a lift that keeps the car’s weight on its tires. When struts have a lot of wear on them, full extension of the struts–such as what takes place when lifted on a chassis lift–can cause struts to be damaged.
You did not tell us how old the vehicle is, or how many miles are on the odometer, but I would suspect that your rear struts are also worn at this point. I would advise replacing both front and rear struts at the same time.
