[Trigger] Problems with applying indexing system in 3 triggers

[Jay the Editor]

Active Ability
Spell Type : Single Target
Cast Range : 100
Lyner grab hold of a target and toss the target high up in the air then shoot couple of arrows to the target.
Level 1: 1.5 seconds in the air
Level 2: 2 seconds in the air
Level 3: 2.5 seconds in the air

As everyone know, Hanky's dynamic indexing system is great but somehow I don't know how to apply it when facing 3 triggers.
Here goes the trigger:

Hypershot cast

Okay, the problem is that this spell works for single caster only. When 2 caster cast this spell, one after another, it floats up properly but somehow when the first target drop down, the second target drop down too although the duration haven't over. I guess the third trigger got problems as it uses the same index as the second trigger.
Can anyone help me with this?

EDIT: Solved.
