It's not blocked out, it's above it, there it says in the center. Above C2 it says center (sentaa, センター). If it's the blocks on the side, then is says アリーナ (arena).

Like I said before Yokohama Arena is quite confusing, you just have to look at the right things. I found it by asking the same question, what is the difference on the ticket? By comparing a few, I found the answer. センター　or アリーナ.
