Hi @Robert6879
The guest favourite badge isn't given to listings that meet specific targets (like Superhost is for hosts). It's simply a ranking - the top listings in your area (according to the aspects that are measured) are guest favourites. The guest favourite list updates every 24 hours, so a listing can drift in and out of it all the time (unlike Superhost, which is only assessed once a quarter).
In this case one of the criteria may have temporarily dipped for your listing, or increased for another listing. The fact that you now moved just outside of guest favourite status, means you can just as quickly move back in (when your listing picks up again, or another one drops off a bit). The badge could be back tomorrow.
Here are the criteria (quite vague, but enough to get an idea):
