I've got a question.. Here is the screenshot of one of the bets I made playing roulette. This one is with play money, but the same thing happens with real money.

As you can see on the photo, I bet 20 play money on two columns on which the payout rate is supposed to me 2:1 (meaning that in case I win, I should get 60 play money per one column - 20 from my initial bet that I didn't loose and 40 because the payout rate for that field is 2:1 and 20 times 2 equals 40). But on the photo you can see that it says I won only 40 and my balance was credited according to that. So in other words, I'm missing my 20 play money and the payout isn't really 2;1, but 1:1.

Am I wrong?
