ni-max showing instruments not connected

[Baubdaluzer]

Just installed two new GPIB-USB-HS+ controllers on a fresh Windows 11 laptop. Installed NI-488.2 and NI-VISA packages. When searching for equipment on the bus, I can see the correct units, but also 30-ish "ghost" units that are not attached (see below):

I have uninstalled and reinstalled the drivers and hardware. Any help appreciated.

Thanks,

Looks like this has happened to others in the past as discussed in this post - https://forums.ni.com/t5/Instrument-Control-GPIB-Serial/Ghost-GPIB-instrument-in-NI-MAX/td-p/3791647...
