Opponent's Graveyard after game finished not resetting

[carlschoeneich]

When I finish a game my own Graveyard is hidden and in the next game the Graveyard starts completely new (how it should be).
My problem now is that if I use the Graveyard for my opponent as well it doesn't hide after a game finished and it doesn't reset either. Instead I get multiple Graveyards below each other for my opponent.

Would be great if that may be fixed.

EDIT: Just recognized that the own Graveyard isn't always hidden after completing the game. Would be great if that could get some consistency as well.
