Replying to Destructo bushings

alright, i just bought a pair of new destructo's, and i skated them for like a half an hour, and i noticed that whenever i landed a little to the left, or kickturned to the left hard the bushing would get stuck under the truck and i would have to pop it back into place after every trick. It also happened to the right. I tried tightening them alot and loosening them alot and the same thing kept happening. Is this a factory defect or does it happen to all destructo's , caus this has never happened to me before. Also, is it because i need new bushings?
