They're best-of-3 sets of games per round, so in round 1 you play your first game with a DPP team, your second game with a BW team, and your third game with whichever you'd like...unless I got it horribly wrong, which I don't think I did.
In terms of the OP I would recommend changing the words "Round 1, Round 2, Round 3" etc. to game or match in order to [hopefully] prevent further confusion.
