You must think in nights, not days.
Your min stay for 2 nights affects booking for Fridaynight and Saturday night. So it must be applied to only those dates (Friday,Saturday). When booking on Sunday, it is then as normal (1 night)
These is another option if you want this to be general:
- goto "availibilty" menu, section "trip details", section "trip lenght"
- choose: "Customise minimum stay requirements by day of week"
- set minimum stay for each day of the week
Hope this helps,
