Broken UVs when importing single fbx

Hello, I have this problem. When exporting the character in FBX from maya and importing it to Unreal Engine this happens with the UVs, one part (the clothes) is imported fine but the UVs of the body are broken. Any idea?

I tried to export it again separately but I keep getting the same problem. I checked that it is something in Unreal because when I import the separated fbx to a new Maya scene, the UVs look fine.

PS: It is a single FBX (“personajeTEST” as you can see in Maya) composed of two parts, body and clothes.
