Leaves appear to have an outline using Surface Appearance

[meepdude49]

I’m attempting to make a stylized tree, but the leaves appear to have a slight outline when viewed from a distance. I know this is a thing with Roblox’s engine but I don’t want this outline on my trees and I am wondering if there is any way I could edit the leaves texture so this outline wont show up

Closer up it looks fine

But further away the outline appears

If there’s any outline on the texture/decal the further back you go it becomes more noticeable
ex: Its super small on this decal but from afar its all black
(im not talking about the concrete)
