/playsound not working correctly with [x] [y] [z] when using "Tab"

The command /playsound is working good, no error and very useful.
However, when I using "Tab" to auto-complete the line of the [x],
its use instant the [y].

and then in the [y], its using the [z].
(Both in command block and player command line)

Please fix it.
Its skipping the [x] line.

{The Attachment are the command /playsound when pressing few time "Tab". (The X,Y,Z in the Debug is not the same as in the command)}
