When activated, the minimum price rule does not seem to generate the desired prices.

We have a 2-night minimum across the portfolio, but choose to activate the "minimum price rule" so that website users can choose a 1-night stay if they are willing to pay the 2-night rate. However, the price shown for a 1-night stay always seems to be higher (sometimes significantly higher) than the price for the same stay extended to 2-nights. Something is off.
