UV Not Properly On Sword Mesh

Hello, I’m new to modeling and using unreal engine 4. I tried creating a sword for my first time. This is the results in Substance Painter.

Worked fine exporting the model from 3ds Max. I was able to edit the UV in Substance Painter.

But, when trying to import the mesh to unreal engine 4.17.1.

I don’t know how to fix this, been searching on the Internet. Watching Youtube videos, nothing really works. I can share my files here, the source. Can’t share, Substance Painter, but the 3ds Max I can. https://ufile.io/95ure, 3ds max project file. Images I’ve exported here from substance painter here. https://ufile.io/vr4a7 https://ufile.io/i50f7 https://ufile.io/bjduo model here https://ufile.io/7xcqw

Someone please help me figure out why the UV does that?
