Measure won't display in a Visual when adding a grouping used in the measure

[Anonymous]

I have a measure which correctly-ish calculates the average of "Story Points Delivered" ([SPDelivered]) over the last three sprints.

Velocity = 
VAR esprint = MAX('dim iterations'[SprintNumber])-3
VAR lsprint = MAX('dim iterations'[SprintNumber])-1
RETURN
CALCULATE(SUM('fact workitems'[SPDelivered])/3,
FILTER('dim iterations','dim iterations'[SprintNumber]>=esprint && 'dim iterations'[SprintNumber]<=lsprint),
ALL('dim iterations'[SprintNumber]))

I can see the measure displaying as I want it to in a table, when grouped by AreaName or TeamName (from related tables), but not when I add the SprintNumber from a different related table, which I have used in the measure.

The same happens if I display in a column visual. Works fone for TeamName and AreaName, but shows nothing when I want to display it over SprintNumber:

The Data Model looks like this:

That works! Thank you very much kind sir.

@Anonymous , Try like

Velocity =
VAR esprint = MAX('dim iterations'[SprintNumber])-3
VAR lsprint = MAX('dim iterations'[SprintNumber])-1
RETURN
CALCULATE(SUM('fact workitems'[SPDelivered])/3,
FILTER(all('dim iterations'),'dim iterations'[SprintNumber]>=esprint && 'dim iterations'[SprintNumber]<=lsprint),
)
