dmidecode -t slot always shows same Bus Address

[LinuxPersonEC]

I even compiled version 3.6, on CentOS 7.9 why would the slot bus address always be the same? Does the CPU being AMD EPYC 7662 have anything to do with it?

/usr/local/sbin/dmidecode -t slot | grep -E "Designation|Usage|Bus Address"

dmesg does show the devices:
