Hello @Giorgio215,
You don't say which of your 5 listings has the problem. I presume that it's the "Luxury sweet home on campo Dei Fiori" one as, after investigation, that seems to be the only Airbnb Plus one.
I searched for accommodation in Campo Dei Fiori and your listing showed up when I was logged in. It doesn't show when I'm not logged in. As instant book is turned on this suggests that you have set the "Government-issued ID" or "Recommendations form other hosts" settings.
If one or more of those is set then you'll have to log in while searching and have the requirement yourself.
If the above doesn'e explain the problem then you;'ll have to contact Airbnb support to discuss the issue.
Steve.
