I wouldn't worry about it. You can re-season if you like, but I doubt it's really necessary. I think it will take care of itself after a few bakes. I usually scrape mine out with a metal spatula, rinse them with hot water, and throw them back in the hot oven and let the oven and pans cool together - and that's it. There is a bit of build-up on the sides, and my pies don't stick.
