Normal Map diffuse texture don't match up on EA cas item?

Heya!

I'm working on lowering the rise of the Bowling night male jeans, AND

I've noticed the Normal Map and the Diffuse don't line up defaultly

Ie the top part is stretched up higher than EA's original diffuse texture.

Are they supposed to be different or is it okay if I make the Normal map perfectly lineup with my altered texture? Thanks !
