So here's what happened!
You did earn the gold, quite right! You also earned the Bronze. How did you earn both? Well, at some point you may have been visiting over in Europe on vacation. If you logged while there, you may have stumbled upon the .co.uk Tom's Hardware rather than the .com US version. Which means that you earned a Bronze in the UK site, with a Gold in the US.
People in the UK should see you as having a bronze, while folks in the US will see you as having a gold. Mystery solved.
