I've had that happen with some no tangle line. I think it because the inner core is stiff to help make it tangle resistant but when folded it can poke through the outer sheath. That's what happened to mine anyways. The hernias are a problem if you want to slide a hitch over it. I'd consider complaining and getting replacements or just get some new line like zing-it.
