Problem with being a spectator

[Demian87]

Trying the following scenario:
I'm an admin. I join a server with my collegues. The new round is started. Then I press a button, that I want to be a spectator. I can see no more cards to choose and I'm marked in the list as a spectator, and the "Spectator" button suggests me to become a player. Everything is ok in this round. The round is over and I start a new one.
Error HERE ---> In the new round I can see the cards to choose, but I'm still marked as a spectator in list and the button suggests me to play.
If I press the button, the cards will desappear, and I'll be still marked as spectator in list.
I think i should be marked as a spectator in the new round too. I should be a spectator until I uncheck this state by myself.
