Array List initial value not set

[Quy]

Creating an array does not set the initial value.
In this example, it should be A.
Add in Array List adds B.
Here is the output, missing A.

{"list":null,"":null,"temp":["B"]}

PS: For Create, Add and where applicable, maybe disable Output Action Step icon as they return null.
Set Array List Index does not output whether Output Action Step is toggled or not so disable Output Action Step icon.

The initial value should be a value of the whole array. So it should be another array not a single item.
It can be also another collection like a result from Query or API Action
