Bing query works with week (mon-sun), not with week (sun-sat)

Hi,

I have a query in one of my template documents that requests this info:

Metrics:["Impressions","Clicks","Spend","AveragePosition","Conversions","Revenue"]

Dimensions: ["Yearweekiso"]

This query runs fine. However, when i change the week to sun-sat, it returns the following error:

Error: Incompatible fields Yearweeksunsat, Impressions, Clicks, Spend, AveragePosition, Conversions, Revenue IllegalDimensionMetricCombinationException

I don't see why the query wouldn't work when you change the weekdays. Could you take a look?
