Mine does the same thing. If you tighten the blade, it will pull it toward the center (when closed) but it doesn't flip as easily. I don't mind it being off center, as long as the blade doesn't rub against the liner.
The edge also seems to be chipping. I gave it a good sharpening and it happened again (cutting pegboard) I am going to reprofile it to 30 degrees and see if that takes enough of the factory edge off to keep it from happening again.
