Get-LocalGroupMember -Group Administrators bug

we stumbled on the following bug.

I think there is the problem, that a non existing SID is in this group, and it cannot be skipped.

PS C:\Windows\system32> Get-LocalGroupMember -Group Administrators

Get-LocalGroupMember : Failed to compare two elements in the array.
