All About Wallbreakers (Please fix)

So yesterday, I made an attack on clan wars (I used gowiwi with wallbreakers) and after I dropped my golems, I'll be spreading some wizards etc. But when I dropped my wallbreakers, they didn't went exactly on the wall I'm expecting them to go. I want them to go on the corner of the box-type walls (with another box on both side) and what they did is go on the "Arms" of the corner-wall. So I dropped all of them (for the rage to take effect on both golems and wb) and after they broke the arms of the corner-wall is the time they broke the corner wall.

What I mean is they broke a "single wall"! They should've gone atleast on to the next layer of the wall with 3 walls or more but, ONE WALL? How will it be strategic if we don't know where the troops are going or what they are capable of. We can't control barbarians, archers, wizards, and witches etc. At least, we must know where the wallbreakers will go. Thank you!
