Right now my listing is not coming up at all as being open for certain dates during Jazzfest. Why is that? It is certainly actively listed and I just confirmed a booking yesterday for the previous weekend. On my listing calendar, it is clearly wide open but when I search for available 3br April 28- May 1, it doesn't come up at all.
