Can anyone tell me the difference between these two tournament achievements:

"10 won tournaments of 50 game types" = win 10 public tournaments in 50 games

"10 won tournaments of 100 game types" = win 10 public tournaments in 100 games

The difference seems obvious, in that the second one, you need to win 10 tourneys in an additional 50 game types. However, on my achievements page, I have 49/50 for the first one, and 7/100 for the second one. Shouldn't these be the same number (the second one should be 49/100)??
