99 Mickey Mantle fielding

[Xshadow77X]

I dont know if it’s a glitch or not but does anyone know why it says Mickey mantle has gold fielding when there’s a fly ball hit to him. I have him in center field and obviously he has diamond fielding. But in the circle it says gold

That is just fielding. Not overall defense like reaction, arm strength etc

And when you prestige him, his fielding rating jumps to diamond for CF.
