Can't see all Office admin templates in GP Editor on AADDS

I am trying to control Office configuration settings through Group Policy on WVD session hosts that are joined to AADDS. I have one WVD acting as my administration console and I'm running Group Policy Management Editor from there. I copied all ADMX files and the en-US ADML files for MS 365 Apps For Enterprise / Office 2019 / Office 2016 to C:\Windows\PolicyDefinitions. I should see all the Office applications in the GP editor, but all I see is "Microsoft Office 2016 (Machine)," "Microsoft PowerPoint 2016 (Machine)," and "Skype for Business 2016." Why am I not seeing Word, Outlook, etc?
