Exchange Online delegation entries not showing group objects

All,
I am only now learning that the Exchange Online mailbox properties "edsva-ExchOlMsExch-SendAsTrustees" and "edsaAzureMailFullAccess" (and possibly other properties; these are just the first two I have validated) do not display group objects that are added as delegates.

I can confirm that groups added are reflected on the mailbox in the Exchange Admin Center, but they are just not being displayed in the web console (or the MMC console) delegate lists.

Is there something I can do to change this?
