When reservations are booked via Airbnb, guests have the option to add other travelers to their trip. When other travelers are added and they message the Host, their messages come through Uplisting on the HOSTS side and HOSTS color (grey) in the messaging tab. You have to look at the profile picture (if applicable) to see who sent the message. Notifications also come through from the Traveler that sent the message NOT the booker (the name on the Uplisting reservation) which can be confusing and make it difficult to track down the message. Requesting ALL messages from guests show up in the messaging tab on the GUEST side in the GUEST color (white) and that somehow the bookers name can be attached to notifications.
