Seems to work fine here, even when using the EAC UI. Make sure you have the necessary permissions, and as a workaround, you can also try doing it via PowerShell:
Set-UnifiedGroup groupname -EmailAddresses @{remove="******@domain.com"}
Do note that you cannot directly remove an alias which is set as Primary. You have to set another one as primary first.

i try to remove an old alias address from a renamed unified group but in the admin center i get the message unified groups aren´t supported (see screenshot). Domain Names are blacked for privacy.
My setup is hybrid where the unified group was created as a Teams in Azure only.
The old group name was hr@.... that is the alias i tried to remove here.
