What happened here?

Edit: I think I know what happened. I might have accidentally clicked to close a position instead of cancelling it at a very bad point in time :/


Hi, I was trying to make some bets today on the David Haye fight, not really trying to trade but just trying to get used to the software. I especially tried to back some lay bets and lay some back bets. I don't know how you call that, basically providing liquidity instead of taking it. Well anyways after some trading I look at my matched bets and I am confused by following entry:
Fights 07. November / Valuev - Haye / Who wins? Draw or Tech. Draw
Back bet XXXXXXXXX 07-Nov-09
12:10 1,01 0,46
07-Nov-09 12:10

Fights 07. November / Valuev - Haye / Who wins? Draw or Tech. Draw
Back bet XXXXXXXXXX 07-Nov-09
12:07 50 19,54 07-Nov-09 12:09

The 1,01 and the 50 are the required level, 0,46 and 19,54 is the money I bet.
So I was trying to back a lay bet at 50, which seems to have worked out at 12:07. I risk 19.54 to win 19.54*49 in case of a draw right?

Now my original order of 20 wasn't filled and at 12:10 the remaining is filled at a level of 1.01. How can this happen or am I interpreting something wrong? I am really confused
