I wonder it the jaws looked bad or were incompatible in some way when they installed the meter and they put some add on doo dad in there.
You could call in a "change the main breaker or tighten the lugs" deal, cut the seal and take a look if you were that curious. I know it is wrong but I have heard guys use that dodge to replace a panel without a permit. It usually takes a day or two for them to get back with a new seal.
