Glyph of Alchemy giving wrong material type?

So I gather from a tree that would normally give green wood logs.. I get soft wood logs instead. This is normal from my understanding with this glyph. Same thing with Elder wood, I get Ancient wood logs instead. However when I gather from ore nodes. I get Soft wood logs from copper, and seasoned wood logs from iron. I would think I would get silver ore from copper, and gold ore from iron no?

You're correct, that's how it should work. It shouldn't give wood from mining nodes, that doesn't seem right.
