Errors with AB Trends tool: data is not consistent with the test start date

emilio

I am getting the following errors with the data I'm trying to pass through Ab Trends:

AB Trend (2) AB Trend: The range of the dates in the data is not consistent with the test start date and/or the number of periods to base the trend measure on and/or the reporting period of the data.

I have a test period that starts on April 29, 2016, 12 weeks of testing, and I'm trying to compare those 12 weeks to the year prior (2015). 

So I have included 12 weeks prior to April 29, 2015 for that extra data (a year + test period (12 weeks)). However I am still getting the error above without much insights after a few hours of chewing into it. 

Any help would be appreciated! Data included
