I'm wondering if the issue isn't the bedside but where the floor was cut in both the front and the back, perhaps the preportions are incorrect and it is throwing everything off, for example if it's an inch too long in the front and an inch to short in the back then the wheel wells wouldnt line up, I'm just spitballing here.
The only way you can know for sure is to measure someone elses shortbed or try a known good bedside on your floor.
