@Robert-and-Vivian0
I checked your listing and your calender shows "min. stay varies". I'm guessing that under "Trip Length" maybe you have set some personal "Additional Requirements"???
I see Aug 25, 26, 27 blocked, so your listing will not show in any searches for long term stays that include those dates.
If I put in a start date of Aug 28, then the min requirement is 14 days (Sep 11) but max is only up to Dec 27 because Dec 28~Jan 11 are blocked. Also Feb~Mar 2018 are fully blocked. And your booking window seems to be 12 months into the future.
You should make sure ALL your settings are consistent to reflect what you want. Hope this helps~
