If it happens to your this consistently, there is a good chance you are aiming the grenades wrong. As far a I know, the damage done by the grenades also depends on the position of the infantry in the house. If you are throwing it to the wrong position, its chance to deal very little damage is higher of course.
A replay would really help so we could see if this is the case.
+1. Grenades go where you click, not just in the building. Aim for the window with the MG.
