GFU_Generic usage is ignored because it is unknown what this could be good for. For importing categories, field usages GFU_Name + GFU_MinMax or GFU_Name + GFU_Min + GFU_Max is needed. For importing color rules, GFU_Min + GFU_Max + GFU_RedMin + GFU_RedMax + GFU_GreenMin + GFU_GreenMax + GFU_BlueMin + GFU_BlueMax (8 fields) are needed, or GFU_MinMax + GFU_Red + GFU_Green + GFU_Blue (4 fields).
