If you put the sgBullet2 action under the spawn sgBullet2 action and sgBullet3 action under the spawn sgBullet3 it should work better.
Also you should spawn only sgBullet instances and change their angle.
No need for two object types duplicates. (sgBullet2, sgBullet3)
On left click

-> Playershotgun Spawn sgBullet
-> sgBullet set angle player.angle - 35
-> Playershotgun Spawn sgBullet
