Fixing EA clothing with improperly applied normal map

Hello, 
I noticed that the forbidden sweater from Nifty Knitting pack has badly done normal map for the male frame. The details that are meant to be on the lower hem and the hat are instead displaying on the torso. The female frame version looks ok. Pictures for reference: imgur.com/a/pMYvIDU

I'm not sure what exactly determines how normal maps are applied. So far, I've always worked with square 1024*1024 normal maps, but this one is 1024*2048 rectangle that exactly matches the diffuse map and both frames have the same one. Ive tried three fixes:

1. Remove the hat and hem part from the normal map. This works, but it's only a partial fix, since the hat and hem itself remain without details.
2. Clone the female version, switch to male and import male meshes. This made the normal map properly applied, but the mesh was slightly distorted and the arm position was wrong.
3. I compared the CAS parts in warehouse, the male has AdditionalTextureSpace set as UpperBody, while the female has it blank (displays as 112 in Text). When I change the male one to Hat or Hair, it has identical results as solution 1., but I can't make it blank like the female one.

Does anyone have an idea how to make AdditionalTextureSpace blank, or if that's not the solution, then how to properly fix this? I suppose I could file a report to EA and hope it gets patched, but I wouldn't hold my breath for a four year old stuff pack.

Thanks for any help.
