We have found significant differences between the low temperature magnetic orders and the magnetization curves below $T_{CO}\\approx 250 K$ of the two samples. In particular one component of the magnetic moment presents a ferromagnetic coupling between the $(0 0 1)$ planes ($P bnm$ setting) deviating the angle between neighboring $Mn$ ions from $180^o$ (perfect CE order) to $150^o$ [$\\delta=0.02(1)$] and $130^o$ [$\\delta= 0.04(1)$].
