Nuendo 13 incorrect panning in VST MultiPanner in bed tracks in projects using external renderer

[MAS]

However, panning a track that is routed to the bed results in incorrect behavior (panning to rear causes output to side speakers and panning to sides produces output to rear speakers).
Panning is correct for Objects.

This is an old problem that has been discussed here many times.

In Nuendo, the order of surround channels and side channels follows the specification of Microsoft Inc. To meet the Dolby requirements for side surround channels and surround rear channels, swap the device ports of the surround channels and the side channels.

In Nuendo, the order of surround channels and side channels differs from the Dolby specification for side surround channels (Lss, Rss) and surround rear channels (Lsr, Rsr). To comply with the specification for the external Dolby Atmos Renderer, swap the device ports for the surround channels and the side channels.

When I create the bed in the ADM Authoring tool, it does not (as far as I can tell) create the Object Bus automatically,

Object busses can also be automatically assigned when using external rendering.
