@kborowinski what is the module name for the Show-KBComputerReport command? I need that to reproduce the issue locally.

[kborowinski]

@daxian-dbw I have prepared short test case. It has the same outcome. Paste following code and try to invoke parameter help on Server property:

function Get-Report {
<#
	.SYNOPSIS
	Display status of the domain joined computers.
	.DESCRIPTION
	The Get-Report cmdlet displays status of specified computer, group of computers or all computers in the domain.
	You can specify additional parameters to fine-tune the query.
	.PARAMETER Server
	Specifies Windows Server type.
	Possible values for this parameter include:
	Any     - any Windows Server type
	W2K3    - Windows Server 2003/R2
	W2K8    - Windows Server 2008
	W2K8R2  - Windows Server 2008 R2
	W2K12   - Windows Server 2012
	W2K12R2 - Windows Server 2012 R2
	W2K16   - Windows Server 2016
	W2K19   - Windows Server 2019
	W2K22   - Windows Server 2022
#>
	[CmdletBinding()]
	param (
		[String]$Server
	)
}
