Hello! I believe this happened after one of the updates, or when I switched to the date picker for date availabilities. Now the date selection in the search bar shows all listings no matter what date you select, even if that listing is not available on the day(s) you search.
The expected result is that only listings with availabilities should show up when a certain date is searched for. I have a screen recording searching for Feb 20th but the listing that comes up does not have availability on Feb 20th, but it will not let me add a video to the thread.
Please disable third-party plugins and customizations (if there are any) and check if this issue persists. If you use a caching plugin, make sure that caching is disabled for logged-in users.
