Collectible Card Game Headquarters

Describe the Bug:
After refusing to pay the upkeep cost the token stays on the battlefield.

What exactly should be the correct behavior/interaction?
The token should be exiled when Dance of Many leaves play.

I confirm this. Also the "When the token leaves the battlefield, sacrifice Dance of Many" ability doesn't work either.
