Predict Projectile Path (Advanced) Doesn't feedback a Phys Mat surface type other than default?!?

To start, this is for weapon shooting.

I first used a Line Trace by Channel, and it worked great, it gave me feedback on surface type and all the things I needed, yet I wanted bullet drop so I opted for Predict Projectile Path (advanced).
Everything works great as far as hit results, except for the “Phys Mat” doesn’t reference anything on collision, and when I grab “Surface Type” straight from the Hit Result like so in the screenshot, it does feed back a surface but it is ALWAYS default.

I have return material on move checked but because I am NOT using Event Hit I think it’s irrelevant.

Any ideas on why a line trace will return a surface type but the projectile path wont? And what I can do to fix it?

Thank you

Bump!
