Unable to calculate road with custom charger

Since few week i’m unable to make a road from one point to another using only prefered chargers. I used to configure my account with only Tesla supercharger. It works for some trip, but since May, when i calculate a trip, i have always other charger, not only Tesla that i want.

By selecting theme manually on the map , it works, but could you check why we can no longer only travel with selected charger ?

my example :

Evry, Ile de France to Etaules, nouvelle aquitaine.

In the past, it purpose me 2 stop on Tesla only. Now, i have 2 or 3 stop and with other charger. (i have the same véhicule Renault 5)
