That sounds like they aren't sealing properly. Did you watch the process from start to finish? Maybe plugs got switched and you got someone else's (or maybe the mold got pinched or ...)
I'm pretty sure the guy who fit them wasn't dealing with any other customers at the time, or maybe, that day. Place was empty and I think he came in just for me. I messaged him but never heard back so I'm kind of writing it off.
