Problem with Teacher profile

Hi I have installed Opigno, and some extras, as a gradebook, I use the spanish translation, also I traduce some words on the platform the problem is this: I have delete all the default profile as a teacher, student, etc, and create new profile with spanish name (Docente = Teacher), (Student= Alumno). When I try to add or modify existing class, this message appeears "You should have at least one teacher" and I can't do anything.
