Displaying of logical name (class charge, attribute unit_charge_type, element commodity_reference)

Hello,

I am reading an electricity meter with the following structure:

class charge, attribute unit_charge_active, element commodity_reference with a logical_name of 1.0.15.8.0.255 (Total energy).

Reading with Gurux, in the section Commodity Reference Type, field "Target" remains empty. Expanding the field "Target", there are the only references to the Credit instances.

In the bluebook, section 4.6.4.2.5 Note 1, there is an explanation where the commodity is the Active Import Electrical Energy (not an credit instance), in the same Note 1 it is a inference that the commodity_reference is an instance of class 3 (Register, scaler_unit).

I consider (with the references to the Bluebook) that the commodity_reference is not a credit instance, it is a register instance and Gurux is not displaying correctly.
