Same Audi PN but one wheel is FUNDO other is Ronal

[dukati]

So is this normal or should I be worried. Same wheel style and Audi part number. Though one is made by Ronal and has PN printed on outside of wheel in hub area while the ones made by FUNDO have it printed on inside. Same size, style, offset, etc, etc. I have pictures if needed but wondering if this is a normal thing sometimes from VW/Audi.
