I just installed the passenger side one and didn't notice any problem with the step that you're seeing. May have been a different supplier, but I did notice the angle on the rocker end was a bit off. Just bent the tabs toward the rocker to adjust that.
The end you're showing looks like the one that goes to the tranny opening, because I don't see the reinforcement around the hole where the cab bolt goes thru the floor. Are you installing it in the right direction? The tranny cover is recessed a bit, so needs more of a step in the floor support than the outer end. The pic I borrowed from RockAuto shows that the rocker end has three tabs, but only two on the transmission end.
You can flatten that step a bit if you need to with a hammer and a sturdy anvil. Beat on it and check the fit, and beat a little more if it needs more adjustment.
[on edit] Added a couple more pictures of my cab support clamped into position.
