can't assign geometry or algebra level I to my classes

Hi

I am a french maths teacher and I try to assign geometry level I to one of my classes: I see well geometry level I in the courses list but when I want to assign it to the class I can only see the level II (in what is called "domaine d'étude" in french maybe study domain in english?). It is the same for algebra II, I can't assign it to my class to have their progression.
