What you're seeing is the result of having arrival/departure dates that span multiple rate periods. The problem is that having multiple rate periods within the same quote creates ambiguities.
For instance, suppose you have a 10 day quote where the first 3 days are in rate period A and the last 7 days are in rate period B. Also suppose that you have a "week" rate set up in both rate periods.
There are multiple choices for how you may want the rates to turn out:
1) You might want the guest to get a "week" rate for the first 7 days, leaving the last 3 days to be charged as individuals "nights". The problem is that since that first "week" falls over two rate periods, you'd have to pick which rate period applied.
2) You might want to ignore the "week" rate since there were multiple rate periods and just calculate each set of days inside their rate periods. In this example, that would mean that the first 3 days were calculated as individual "nights" in rate period A and the last 7 days were calculated as nights or a week in rate period B.
3) You might want to combine both of the previous two options and calculate a prorated "week" for the first 7 days based partly on each rate period, adjusting for the cost difference.
Currently, OwnerRez calculates all rent rates based solely on ONE rate period - which is the rate period that the first night falls in.
In the future, we'll be adding an option that will allow you to pick whether you want dates spanning multiple rate periods to be broken up per period. If you choose this, charge types (weekly, nightly, etc) will be calculated as a SECOND priority to that.
Hope this helps,
