problem of group option in multinomial case

[yzy1015]

Hi
It seems like there is a problem with group option in multinomial example.
when I run following command, mtype is grouped.
cvfit = cvglmnet(x = x.copy(), y = y.copy(), family='multinomial', mtype = 'grouped');

After cross validation, in cvfit:

'dim': array([30, 71]),
'grouped': False,
'jerr': 0,

grouped is false.

Thank you
