When I try to use Get-Help with any of the aboutActiveDirectory* topics, it just gives me a list of cmdlets. Other topics, like aboutFor or about_Break work as expected. I had originally thought it was perhaps an interop issue with PowerShell 7 being installed as well, but it happens when I try it on my Domain Controller that has only the PS built in to the server. An example is below:

PS C:\Windows\system32> Get-Help -Name about_ActiveDirectory

When adding values in a multi-value field (such as the serialNumber attribute), the editor sorts by alphabetical order. When adding values via PowerShell, order is the order in which they were inserted.

The order in which the editor displays is not a filter, but modifies the true order (to where even PowerShell displays them that way). Without this order, the positions are useless. One could use a MV field like a simple one row spreadsheet (using ordering like column positions). The only way to make it useful is by making it a key/value pair (e.g. model:12345), and this basically defeats the purpose of the multi-value datatype.
