It's just one of the many changes they made in the series from the movie. There are a few, though the only other one that stands out at the moment is that the movie states that Abydos was in another galaxy, while in the series it is very obviously in the Milky Way.
The movie placed the Gate in the fictional "Creek Mountain", while the series quietly relocates it to the real-life Cheyenne Mountain.
Daniel's wife was named Sha'uri in the movie, and Sha're in the series.
The name of O'Neill son changes, but to be fair, it was only seen briefly in writing in the movie.
