BUG OR LOWER ROUND REALLY (B01)?

Is there truly just going to be B01 for lower round 1 of Masters Madrid, or is the information posted on VLR incorrect?

surely a bug

given that the next lower bracket game is a bo5 I think its safe to say thats gonna be a bo3 (otherwise they would have done 2 bo3s instead of a bo1 and bo5)
