Is anyone else having division changing problems?

[Saren]

I have finished exactly 3 games since the beginning of season 2, and I'm pretty sure I have been in a new division after each game, but all of them still in Master's. First I was placed in Silver Hand, then I moved to Yellow Stone, and I thought I must have just been wrong about what division I was originally in. But I have finished another game and now I am in Ugly Nest. I'm pretty sure I'm not imagining it this time.

I am so confused. Is this happening to anyone else? Is this a bug or is it an intentional part of the new system?
