Game rating -System incorrect

When setting a rating for a few games i noticed that the ratings have been set to the incorrect system. i.e. All the games i rated were for the pc but a couple show up as ps3. Is there anyway to fix this?

Also how do i rate a game for a specific system in the future to prevent this happening again?

Hi there. Can you please give me an example or two of a game you have seen this happen with?

@digitaldame: I've rated Sonic & Sega All Stars Racing Transformed and Dead or Alive 5 - I've played both for the pc but when i look at my ratings and reviews they are both set as ps3 when i never had the option to select which platform.

We don't currently allow ratings at the platform level - they are only at the game level. If they are showing with an associated platform, that's a bug.
