It sounds as though the square being OK on the outside but off on the inside is a framing square.
As a WAG, there is drop of clear protective finish on one of the legs of the framing square. Just scrape it off and everything should be fine. If there is no globs of finish, take the square back to the big box for another one.
Use the right tool for the job.
