attached are 3 files that demostrate what is happening when I select a profile to loft and the rails of the Surface and how it changes the profile and how I can get a straight back edge not bowed in like it did to the front

I am not familiar with editing jpg files in Inventor.
Why didn't you attach the ipt file?

The entire part seems to me to be poorly done.

I would (almost) never ever use Fixed constraints.
The dimensions don't make logical sense to me?

The arc in Sketch7 used for a rail is not connected to the profile sketches 1 & 3 (this seems to be the biggest problem - taken care of with a simple Project Geometry - you should constrain all sketches).

 

You might add additional rails for more control.
