Measure Showing Blank Value When Using Slicer

Hi All,

Very new to this and running into trouble. I have the following measure created in the Chang Log fact table to calculate the date difference between two statuses.

Time in Dev (s) = 

var DevStart = CALCULATE(min('Change Log (Status)'[Change Time]), filter('Change Log (Status)', [items.to] = "3"))
var DevEnd = CALCULATE(min('Change Log (Status)'[Change Time]), filter('Change Log (Status)', [items.to] = "11046"))
var DevTime = DATEDIFF(DevStart, DevEnd, SECOND)

return DevTime

This is my data tables:

The issue arises when I try to use a Sprint slicer (from the dimSprint) to filter to my measure in the Change Log table. I end up with something like this:

You can see that the Sprint filter works (right table), I get Issue Keys (from Issue Data), but in the left table when I add the measure, it returns no results (I double checked the data and there should be results there).

I am not sure if it is the relationships between the tables or the measure itself. I have tried a few things and still no result. I tried creating the measure in the Issue Data table and it still does not work.

My goal would be to able to filter on dimSprint and show combined data from Issue Data (issue key) and Change Log (my measure)

Any advice/suggestion would be appreciated.
