SetItemCountRequired just doesn't work

The function just doesn’t work. Nothing happens, the values do not change.

TestDevice := class(creative_device):

    @editable Conditional : conditional_button_device = conditional_button_device{}

    OnBegin<override>()<suspends>:void=
        Sleep(1.0)
        Conditional.SetItemCountRequired(555, 0)
        Print("{Conditional.GetItemCountRequired(0)}") #return start item count
