Copying ActiveX Command Button from master sheet to subsheets. command button code missing

Hi, been searching for an answer on this. probably simple or a limitation but i cant work it out

i have a master sheet that i copy into other subsheets. the master sheet has formula's that work on new pasted dated. it all works fine.

I added some Active X Command buttons to the master sheet for filtering and when i create the subsheet the buttons get copied across but i lose the command button code in the original master sheet.

Example of master sheet code for TWO buttons are:

Private Sub CommandButton1_Click()
' command button 1 runs the hide and show trap 1 details
    Application.Run "'greyhounds workings.xlsm'!Trap1show"
End Sub

Private Sub CommandButton2_Click()
'
    Rows("72:119").Select
    Selection.EntireRow.Hidden = True
    Rows("80:87").Select
    Selection.EntireRow.Hidden = False
End Sub

when i click on the button in the subsheet nothing happens. 
when i then go into developer mode and view code for the button i first get any empty "GENERAL" tab. clicking on command button 1 brings up the following

Private Sub CommandButton1_Click()

End Sub

I have done the same for not active x buttons, being Form Control buttons and the button code IS copied across

Active X Command Button code isn't copied across. please help driving me mad
