Get-Acl Returns SIDs Rather than Object Names

Hello.

In Powershell, when I run

Get-Acl [NETWORK FOLDER NAME] | Format-List

It returns only the SIDs of Active Directory Objects (such as security groups) rather than the readable names of the objects (such as "Maintenance Folder Read Access"). In the GUI, using the same credentials, I can see the readable names just fine on the exact same network folder properties.

Can anyone advise as to how to get this Get-Acl Powershell cmdlet to return readable names rather than SIDs?

Thanks
