FirebaseFireStore return true for isSuccess after I try to delete a document that already created

I accidentally found this after I test my application. I have a recycleListView that contains cardview which each one has a document from firestore. After I delete some document randomly, it disappear from FirebaseFirestore, but when I try to delete it again it still return isSuccess() true. Can someone explain me why this happen?
This is my code that I use to delete document from Collection.
FirebaseFirestore.getInstance().collection("Collection_A")
.document(list[position].id).delete().apply {
addOnCompleteListener { task ->
if (task.isComplete){
Log.d("Complete", "Task complete")
}
if (task.isSuccessful) {
Log.d("Complete", "Task complete and Success")
} else {
Log.d("Complete", "Task complete but not success")
}
}
addOnCanceledListener {
Log.d("Cancel", "Delete data canceled")
}
addOnFailureListener { ex ->
ex.printStackTrace()
}
My Document Structure
Collection_A
Docoument… [Document ID generated randomly]
name [field]: String
count [field]: Int
dateInWeek [field]: Map < String, Boolean >

I just quickly tested and it seems that on JavaScript too the delete is considered successful even if the document no longer exists. So it sounds like this is working as expected, and you should probably label it as "the task is successful when the document no longer exists in the database". The task will only fail if you don't have permission to delete the document (whether it exists or not).
If you want to test whether a document exists, use a get() operation.
If you want to atomically detect whether the document exists and delete it, use a transaction.
