trigger adds amount to default back twice....why? please help

I am trying to create a trigger that will add half of the previous P/L to the default back if P/L is less then 0, or decrease the default back with 2 * previous P/L if P/L is greater then 0 and then place a back bet. All this in Hi Lo.

but the triggers i`m setting up are acting twice....for example:

game 1 round 1:
              - default back is 10 
              - back card 1 for 10

           round 2:
               - card 1 comes up and computer predicts

           round 3:
                - card 2 comes up (card 1 is a loser)

game 1 P/L = - 10 

game 2 round 1:
                 - trigger increases default back with 5
                 - back card 1 with 15
and now it should wait for the result...but instead it increases again the default back after the bet has been placed to 22.5.

what am i doing wrong?

thank you in advance for your help
