It's just a small mistranslation. As explained above, it was referring to Leves and Behest.

Here is the original EN for Q30 :

Q: You mentioned that the existing content names would stay the same but the content itself would change drastically. How will leves, behest, NMs and hamlet defense change?

A: There won't be major changes to leves. They are content that you can continue to progress by continuously doing it the same as now. The changes for behest are large enough that we feel it would be better to change the name to make it easier to understand, though.

For NM battles and hamlet defense, we are making content that encapsulates them and will be integrating it into this. Also, we can’t really talk about the specifics, but we are planning to add content to each field area that is easy to join and leave.
The FR Rep translation is based on the EN one.
