Ugh! Seems like a classic case of shortsighted design thinking and cutting corners. We had a number of ceiling fans in our former house and we pretty much universally had problems with all at some point in time with the various settings being off kilter. That said, the fans were not the same model and not even from the same manufacturer. With one, the settings for low, medium, and high speed were actually backwards. It wasn't anything that was dangerous or that we even took time (and expense) to fix. The bother was we had to create kludgy workarounds just to keep them going.
