I'm still not fully convinced that the switch isn't working exactly as configured. There's nothing in the documentation that says "Untagged traffic received on a tagged port will have an 802.1q tag added to the frame header, then sent to any ports on the corresponding VLAN and will not be untagged as long as UntagDefaultVLAN is disabled on the port it's being sent to." Maybe it doesn't insert an 802.1q tag in the header because it assumes you won't want a tag on an untagged packet? There's nothing in the documentation that says one way or another what exactly it will do to an untagged packet through this process, and since the switch isn't working as you expect it to work it seems very likely that it isn't doing what you think it's going to do.

Filtering untagged frames will cause the ports to behave exactly the way you want them to, and it's well documented as the recommended setup. If you want better documentation then you're going to have to reach out to Avaya (good luck), but I think if you opened a ticket with Avaya they will likely tell you that the device is behaving as expected.
