same total for each row

Hello everyone,
I have a question.
I created a table with 2 Measures that work well.
I created a third one to calculate the percentage.
It works if I filter on a team but if I choose several, it gives me the same value.

Measure 1  :Nb Retour Enq EL EMEI Imhoweb BO = CALCULATE(DISTINCTCOUNT('Dossiers IWS'[IdAppel]);'Dossiers IWS'[LibelleAction] = "Avis Client"; 'Dossiers IWS'[YEAR_CLOTTECH] = YEAR(TODAY()))

Measure 2  : Nb Ticket EMEI Imhoweb = CALCULATE(DISTINCTCOUNT('Dossiers IWS'[IdAppel]); 'Dossiers IWS'[YEAR_CLOTTECH] = YEAR(TODAY()))

Measure 3  :Taux de Retour global = [Nb Retour Enq EL EMEI Imhoweb BO]/[Nb Ticket EMEI Imhoweb]
Do you have an idea ?

I make a filter on Libelle_Equipe_Clôture

Thank you in advance for your help
