Query: Snap'n stack doesn't stay "snapped"!

I received a Snap 'n stack for holiday storage, thinking it looked perfect. After snapping the levels together, and lifting by the handle (with nothing in them!) some came unsnapped, causing it to fall. I tried several configurations, thinking it was perhaps one faulty "snap". No dice. I could definitely not put breakable ornaments in here and expect to lift it with the handle!
