PCI addresses not listed in dmidecode on R730xd

Hi,

On R720 the dmidecode command (in Linux) shows PCIe slots and the corresponding PCI addresses.

But on R730xd it lists the PCIe slots, but no PCI addresses.

Any ideas why? Is this the same with all Gen13 servers?

Can this depend on the BIOS version? We have BIOS ver 1.3.6
