By default created games are single symbol, you need to choose option before start to be able to pick double ones.
I don't know why it is not vice versa.

Yes it should default to double symbol. The game is incredibly random and hard with single symbol cards.
Playing with single symbol cards is easier for begginers to learn the game. That is reason for being default. Other players can switch to double symbols.
