Glitch in 990 – Angry Birds Match 3 Review

Stuck on level 990. I clear all the mud and pigs as required, but it shows I still need 3 more mud tiles cleared. There is no more mud visible, but there are three metal boxes. Finally I figured out that you need to hit each of the boxes with a bird. However, it only registers as a hit to the metal box if there are no mud tiles touching the boxes? Super frustrating because it looks like the only way to pass the level is to buy boosters, which I refuse to do.
