It looks like every .2 seconds if your left click is down you are setting all your bullet angles.
I never used spawn object (Only ever Create object) but it should work the same. On the Left button/Every .2s Condition Remove your 3 set bullet angles.
Create a new condition. Bullet on created - Add the 3 set bullet angles.
This should set the angle one time - one creation - then ignore when setting for new bullets.
