It sounds like there's an error in your lacing, and I have an idea what it might be. Looking at the two spoke heads circled in this picture:
The upper spoke looks to be counterclockwise of the lower spoke at the hub, but clockwise of the lower spoke at the rim. So the upper spoke has a much shorter distance from hub to rim than the lower spoke. If you keep lacing from here, some spokes will seem way too short, and others will seem long.
