That "same uniqe ID" problem is weird
Normally there is no "same unique ID". The way to create those: Make a new virtual disk, and then copy the VHDX / VMDK instead of creating a new one.
Doesn't change the diskmanagement tool bug, which is serious, since it should always go by the internal index and not unique ID.
My recommended disk view is a bit more detailed though:
Get-PhysicalDisk | ft DeviceID,FriendlyName,SerialNumber,MediaType,size,uniqueid,PhysicalLocation
The above mentioned "clones" usually have the same serialnumber and friendlyname as well.
