COUNTROWS over range question

Hello,

I'm struggling with creating a measure that does the following:

     Sum the number of occurrences for each incident type for the previous week ending.

I have a table that has the following relevant fields (this is an abbreviated snap of my table):

I am trying to return (for the snippet above, the actual data has more values matching the criteria):

Application = 4

Internal = 4

I created this measure:

RequestTypeCount = CALCULATE(COUNTROWS('Report'),FILTER('Report', 'Report'[Created On] < MAX('Report'[WeekEnding]) && 'Report'[Created On] >= MAX('Report'[WeekEnding]) - 7))

But I am getting extra counts for things I am expecting to be filtered out (values in red I'm not sure why they are being counted):

The total count should be 32 (21 Application + 11 Internal), any thoughts on what I'm doing wrong?
