Strange Result of a measure

[GeekAlfPro]

Hello,

i'm facing a strange result of a measure

I want to calculate the disponibility of a vehicle.

For that i code the following measure

Disponibilité véhicule = 
CALCULATE(
    COUNT('Disponibilité'[Dispo Qualifiée]),
    FILTER('Disponibilité', 'Disponibilité'[Dispo Qualifiée] = "Exploitation"))

But the result is strange, because it displays 45, 

despiste i only have 22 days with the filters...

Hello @Anonymous ,

yes with the same result.

i noticed another oddity.

i have 2 segments

one with a range of dates, the other with the months

the measure is OK when i select the date AND the month, but not if i only select the range of dates

Hi @GeekAlfPro 
have you tried COUNTROWS() instead of COUNT()?
