Hello @James998 ,
Most guest are aware the platform works this way. Also the mininum stay is displayed IN the listing under "availability", just under the section "cancellations" ANDdisplayed just under the booking form.
I do not see 1 augustus as available on your listing "spacious Home etc.." .
You probably have set a custom price for the available weeks, which results indeed in displaying the check in dates only. If you set the price in the calender (or use basic price with discount), then all available days will be shown. Same when choosing "check-out" in the booking form as first date to be selected: it will display all days. So it is clear to guests (for example) they can book in period 6 - 14 august for 7 nights, only to start on 6 or 7 august (and leave on 13 or 14).
best regards, Emiel
