Get-ACL and PowerShell 2

Please … no flames … I really do need to update PowerShell 2 code for legacy air gapped XP systems.

I have this simple example.

$Folder = 'C:\Some\Folder'
$ACL = Get-Acl -Path $Folder -Audit

This works peachy in both PS2 and beyond.

However, I need the audit flags. This works fine in PowerShell 5.1 and beyond

$ACL.Audit.AuditFlags

PS C:\> $ACL.Audit.AuditFlags
Success, Failure
PS C:\>

This does not work in PowerShell 2. I can see the properties exist as such:

PS C:\> $ACL.Audit


FileSystemRights  : ExecuteFile, DeleteSubdirectoriesAndFiles, Write, Delete, ReadPermissions, ChangePermissions, TakeO
                    wnership
AuditFlags        : Success, Failure
IdentityReference : Everyone
IsInherited       : False
InheritanceFlags  : ContainerInherit, ObjectInherit
PropagationFlags  : None

However, when I attempt the same syntax as such, it returns nothing:

PS C:\> $ACL.Audit.AuditFlags
PS C:\>

I can however get the values with another method:

$ACL.Audit | Select-Object -ExpandProperty 'AuditFlags'

PS C:\> $ACL.Audit | Select-Object -ExpandProperty 'AuditFlags'
Success, Failure
PS C:\>

Is this simply a limitation to PS2 and I need to use the longer syntax? I need pretty much all the properties from $ACL.Audit and would prefer to use the shorter dotted notation if possible. I should point out I have only tested on PS2, 5.1 and 7.3 and nothing in between.

Thanks in advance for any help.

Disregard please … I played around enough and found the solution:

$ACL.Audit[0].AuditFlags
