Escalation said it was a known issue, caused by a recent upgrade. Apparently they're "working on it"...
If anyone in the community knows a workaround to get a space to show up as a "room" please let me know.I saw in a similar thread about the opposite problem (entire place listings showing up as rooms) someone figured out that by changing property type from "house" to "guest house" could be used to make the listing show up right in search until the real issue got fixed.
So... anyone know which listings always show as "room"?
