Carpet quality control issues?

[Accelo]

I received this carpet that is for behind the seat in a relocated gas tank 1972 C10 1/2T truck.
I also purchased the floor carpeting. It worked out nicely.
The color match is right on.
However, the way this back panel carpet is cut and sewn makes no sense.
I think it is not correctly cut or sewn. For instance there is a seam in the back about 1/3 down the middle? One side looks good, the other is unworkable.
I am attempting to get it replaced? The local Upholstery guy is know in two states and does excellent work. He replicated my seat covers in the material I wanted for less than the covers would have cost, not including installation. He says he can fix it. I'm not looking for perfect as it is behind the seats. However, I wonder of the quality of employees assembling this stuff.
