So I took the shield off to clean it and then put it back on. Now it won't close properly. When I use the tab or any part of the shield from the center to the left, the right side will slightly pop out of the locking mechanism. The part that pops out is on the front of the lock and I can push it back on pretty easily and clicks into place. Did a break something somehow? I never used a large amount of force to take it on or off. Anyone else with this problem?
