            if(task.isSuccessful()){
                Toast.makeText(MainActivity.this, "Deleted", Toast.LENGTH_SHORT).show();
            }
            else{

Your screenshot shows a collection called "messages" with three documents that don't actually exist. You can tell they don't exist because they are in italics. However, the console still shows them because they have nested subcollections ("shivang") that still exist - the display of the missing document is required so that you can still see and navigate into that data.

Deleting a document does not delete any nested subcollections. You have to delete each nested document individually.

Read the documentation about this.
