Mode.notes('lydian', 'F') output error

[SongXin]

Mode.notes('lydian', 'F');

Now, The output is:
['F', 'G', 'A', 'Cb', 'C', 'D', 'E']

I think, it should be:
['F', 'G', 'A', 'B', 'C', 'D', 'E']

Mode.triads('lydian', 'Fb')  // Fb, Gb, Abm, *Cbbdim*, Cb, Dbm, Ebm
Mode.triads('lydian', 'Cb')  // Cb, Db, Ebm, *Gbbdim*, Gb, Abm, Bbm
Mode.triads('lydian', 'Gb')  // Gb, Ab, Bbm, *Dbbdim*, Db, Ebm, Fm
