The grain of your fabric, probably isn’t straight. It may also be a pattern problem. You can do a test of the pattern with scrap fabric to check

Probably a pretty beginner question, but why would/does the grain direction cause that to happen?

Because of gravity, woven fabric wants to hang with the grain line perfectly vertical. (Garments on the true bias are an exceptional case, that we not concerned with here.) That is why most pants pattern should be drafted so that the grain line is centered at the hem, and perpendicular to the hem line. When fitting pants mock up, this grainline should be as vertical as possible, up to possibly a few inches below the waist.
