There are 3 (and not 4) nonequivalent Pu atoms in your structure and inst
files. The magnetic ordering in your case.inst file is up-up-dn:
^^
||| 
  v
This may not give zero total magnetic moment, as they cannot cancel each
other, if their symmetries are the same.  
The number of magnetic atoms (with similar symmetries) should be even for
doing AFM calculations. If you have 6 Pu atoms, you can define the
up-dn-up-dn-up-dn ordering:
^
|| 
 v 

Maybe you need to make double the structure along Z-axis.

Sincerely yours,
S. Jalali
