@Miri0 Gee, I don't have that at all in my Stats section, but then again you have more features on your device than I have. Perhaps your version is including potential reservation dates that people are searching for in the future. Is there any correlation of the stats with local events / holidays in your area?
If what I suspect is true, I would love to have that information!
You can contact Airbnb to inquire or perhaps there's another host in this Community that already knows the answer.
I will also inquire in another group I'm involved in to see if the expert hosts there understand what this screen is telling you.
Thanks for the screen shot!
