The episode "Party Crasher" has Viperion being called on among other holders to fight a new akumatized villain, and even being called "Viperion" by others. However, this episode (which comes after the aforementioned episode in the American version) has Marinette taking out the Snake Miraculous for the first time and initially making Adrien the holder before finally giving it to Luka who comes up with the name "Viperion." In the French version the continuity is correct because this episode precedes "Party Crasher."
