A chat command was executed twice in an action.

I am using Minecraft for Windows 10(1.9.0) and Code Connection for Minecraft (1.50)

Although the action is one, the chat command was executed twice.

 

The command line in the Minecraft for Windows 10

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

  run

 

Make Code

~~~~~~~~~~

player.onChat("run", function ()

{     player.say("Hi!") }

)

 

The results

~~~~~~~~~~

/closechat

/execute @p ~ ~ ~ say Hi!

/closechat

/execute @p ~ ~ ~ say Hi!
