That's the danger of transferring client files too early. There typically are bugs that crawl out of the software when clients are transferred before the software is really ready to go.
No it won't correct itself. It's ok to transfer a few clients early if you want to play with the software a little, but don't rely on the files. Any files that are transferred early should be deleted and wait until January until you make your client rollovers for the new year.
