Filtering on connects_to_bus_type is not working

[ktvanzwol]

Describe the bug
Filtering on a specific connected bus type does not work.

def print_resource():
    format_string = "{0: <16} {1: <32} {2: <21} {3}"
    with nisyscfg.Session() as session:
        filter = session.create_filter()
        filter.is_ni_product = True
        filter.is_chassis = False
        filter.connects_to_bus_type = BusType.PCI_PXI

        print(format_string.format("Expert", "Alias", "Model", "Bus Type (#)"))
        print(format_string.format("------", "-----", "-----", "------------"))
        for resource in session.find_hardware(filter):
            print(
                format_string.format(
                    resource.expert_name[0],
                    resource.expert_user_alias[0],
                    resource.product_name,
                    f"{resource.connects_to_bus_type.name} ({resource.connects_to_bus_type.value})",
                )
            )

Output is an empty list.

Expert           Alias                            Model                 Bus Type (#)
------           -----                            -----                 ------------

When commenting out the line: filter.connects_to_bus_type = BusType.PCI_PXI the output is:

Expert           Alias                            Model                 Bus Type (#)
