Iron donator showing up as Gold on leaderboards?

[SixZoSeven]

This is not a big deal but I am just curious about it. I am currently an Iron donator. (as you can see under my name) I was looking at the leaderboards and it shows me as a gold donator. Any idea why? lol.

There's been alot of issues with the leaderboards, I've seen rank like 586 inbetween 6 and 7.
