I want to change the name of the element when choosing a trade offer, but these parameters do not get into the array, who knows what the problem is

[JS_OFFERS] => Array
        (
            [0] => Array
                (
                    [ID] => 14262
                    [CODE] => 
                    [NAME] => 
                    [TREE] => Array
                        (
                            [PROP_473] => 851
                        )

                    [DISPLAY_PROPERTIES] =>
