Cannot see distribution list with Office 2016 on Mac clients

I'm supporting a mixed environment of Macs and PCs.  They are using Office 365 and Office 2016.  After creating a Public Folder database and root folder in O365 I was able to create a Contacts Public folder via Outlook 2016 on a PC.  Inside I placed two test users and a Distribution List.   The users are visible on all systems, but the Distribution List1 will not show on the Mac Outlook clients.  It does show in OWA.

This is what I see in Outlook 2016 on the PC:

Any ideas?
