[Issue] Baking Issue, Visible Seam Shading

Hey there! I'm currently making a coffee maker in Substance Painter. 

I have this issue where there's a very visible shading issue at the seam here. It's being caused by the stylized smart material I have applied. Any advice on how to fix this, and what I can do in the future to prevent this from happening again? It seems to have to do with the Base Map or Normal Map...
