Yes, you are right I have 11 live listings. Two of them are unlisted. Either way, none of them show up on my multi calendar. I have tried all filters and searching for the property in the search bar of my calendar, and nothing shows up. There is a glitch in the system that I need to be resolved. I have tried multiple browsers as well.
My multicalender performs as normal. Please be sure no filters are set (the number of filters set appears in the search bar) and no text is entered in the search bar.
You can still manage the listings and their indvidual calenders from menu "listings", allthough rather inconvenient.
If problem persists maybe contact Airbnb, as this community can not solve the issue.
