I think you just clicked on Header condition field in V/06 for those 3 condition's.And when you create sales order system automatically pick the condition records since you had already maintained the condition records, apart from that the same condition types entered manually hence system is showing two condition types for each.
Please note the header condition functionality once again.
1. Header condition should not have any access sequence
2. Since it does not have access sequence you can't maintain condition records, hence you need enter this header condition type manually.
Better to copy those condition types and create new for which make sure that header condition type functionality applies and place these condition types in place of the old condition types ( in your case ZADV, ZPRP and ZRET) in the relevant pricing procedures,
By editing the existing condition types may impact other pricing procedures if any.
