Broken achievements

[Rasharx]

Hello,
I've been trying to get the "Olympic" and "Weapon Master" achievements but they seem to be broken.
I've already tried to beat "Olympic" mode in every possible way (referee, 7 points instead of 8, no falls or touches, etc.) and on every possible difficulty but nothing seems to unlock it. In the same way, I suppose that through that achievement the Olympic rods will be unlocked; so I haven't been able to unlock them for the "Weapon Master" achievement.
