Additional file-related features and issues within Microsoft Teams for Education
Hi Costantino,
The Class Material folder is a default folder when you create a Class team.
So it's not possible to rename that folder.
My idea for your case is this is a display issue, you may go to SharePoint site for this team > Site Settings > Region Settings, check if this site is located in the correct region.
Also, in Site Settings > Language Settings > check both English and French.
Return back to the General Library, see if the Class Material's name is shown in English now.

Many thanks for your quick reply.
Unfortunately, when I created the folder, it was in English: CLASS MATERIAL. It changed to French, after my colleague, another "owner" opened it from her own computer. This is really strange.
