Dear Nadia,
I encountered something similar. Be aware that it might not be an error but could actually reflect the physics of your system. If you are describing an essentially 1D structure, accurate k-sampling is important to reveal the spin-structure.
Don't dismiss your result as wrong, it could be something interesting:)
Try plotting the spin-resolved bandstructure.

Best regards,
Mads Engelund

I must to add that when I do electrode calculation for same system by
setting the following values,
%block kgrid_Monkhorst_Pack
1   0   0   0.0
0   3   0   0.0
0   0   50  0.0
%endblock kgrid_Monkhorst_Pack
SpinPolarized         false


I have obtained the correct Fermi energy.
Thanks in advance.
