Riddles Ridler (Batman: Arkham City)

Pereprohodil once again, completed the campaign mode, completed all the side effects, Nigma caught, but somehow the menu shows that there are 383 of the 400 riddles. The same Cat also has one missing (screen put). No one seen this? This is a bug or I missed something? And yet, your profile still shows 71% passed, this is due to the fact that I test don't all pass? And it is not clear what it means by 100%. Thanks in advance!
