parameter groups

Hi,
Hope you are all well and having a lovely day, I need to make some atomic strobe fixture profiles behave properly, I have modified the standard parameter groups so that strobe rate & duration are classed as a ‘Beam’ parameter rather than Intensity, to make it so they don’t fade with intensity. Sadly when the fixtures are selected in programmer I am unable to select the beam tab, any ideas ?
Best Wishes

Chris
