I am experiencing problems programming MACROS on the TL Xtra. Macros seem to be ok with purely generic channels but the problems manifest themselves when using FIXTURES. 
e.g. 
 Select  PROGRAM Mode 
 Press MACRO 1 the PROGRAM 
Select FIXTURES 1 to 8  ( LED PAR cans in this instance) 
Set Dimmer Channel to 100% 
Set Colour RED to 100% 
Press MACRO 
  
Set all channels to 0, deselect fixtures, go to RUN Mode 
  
In RUN Mode 
  
Press MACRO 1 
What happens next seems to be random. 
Sometime all 8 fixtures are selected and the RED channel set to 100% but Dimmer Channel stays at 0, other times nothing happens. 
  
Have tried reprogramming the MACROS have cleared the MACROS and then started again but I can't get consistent operation. Have updated to the latest version of the firmware but it is still the same. 
What am I doing wrong ?
