Crack propagation mixed mode

I have a problem, I am modeling two cracks that are propagating under uniform stress. In experiment they avoid each other at first and than colapse and in my simulation they meet at the middle without avoidance which is wrong. Can any one tell me what I am doing wrong ?

Picture of my experiment is attached.
I am using KII= 0 criterion for determination of cracks path.
Ansys code for calculating KI and KII for both cracks:
PATH,KL,5,,48 ! Definiranje linije pukotine pomocu koje se racuna KI,KII
KCALC,1,,3,, ! Izracun faktora intenziteta naprezanja KI,KII
