Could someone advice me on why this order open?

I had test an EA which create a pending order
2006.07.28 12:25:03 '1136246': pending order buy stop 0.10 NZDUSD at 0.6165 sl: 0.6155 tp: 0.6185

Order confirmation:
2006.07.28 12:25:04 '1136246': order is open : #8521433 buy stop 0.10 NZDUSD at 0.6165 sl: 0.6155 tp: 0.6185

This order (#8521433) open without hitting the buy price at 0.6165 and at the same time it also close the order which is my stop loss 0.6155. at 2006.07.28 12:28
Order No: 8521433 (Highlighted)

MT4 open and close at the same time, when it had hit stop loss?
But it is a pending order if it not hit the buy price it wont open right?

Could anyone of you tell me why? Or mybe it is my mistake?

THANKS
