Littlewoods Question

So i made my 1st deposit on there this month and got an email saying they paid me for the monthly bonus. for some reason i have 50 pounds more that hasnt cleared yet. This doesnt make sense since the bonus is only 25 pounds. i thought maybe there was an initial 25 pound sign up bonus on top of the monthly, but then there is still an extra 25 in there. I have no idea how many hands I need to clear this mystery bonus either....
