I've experienced this in the past. Thing to keep in mind is that these things are mass produced so its always possible to get a dud from time to time. I've learned early on to save my old caps and tips from bottles I've emptied. That way I have spares in case something happens. I even keep old bottles or use a new empty from my diy supply to substitute for a leaky bottle.
Anyways.. unless you get 2-3 in row that you are having problems with, it was probably just a fluke. If you do have a streak of bad bottles, caps, lids..then its a serious QC problem at the manufacturer.
