After you have edited the headers in the Load Panel go to the top of the load panel where it allows you to select and save presets. Save whatever you’ve just configured as something like “Result Column Order”. Whenever you open GA5 just select that preset and the columns should show as configured for all kits.
I’m not sure if this is the most elegant way to do it, but it works for me.
Basically, it should be saved with the project file in the GA preferences. Could be there is a conflict with your permissions. Please get in contact with our Support Department.
I am still finding that the column orders are not sticking correctly. Even when in the top RH corner my preset name is being shown this can be unreliable. It is easily solved though by re selecting what is already selected.
