[Wien] band plot strange

[Mary White]

Dear users,
           I have some problems when I calculate the energy band. The space group is 152_P3121,which is hexagonal cell.
           The scf is OK. But the band in some special k-points that is in a small range is abnormal. Almost enery bands in the same range have very low values,which are much lower than the energy of nearby k-points. There is something wrong with it. The process I calculated the band is as follows.
        create case.klist_band file
        x lapw1 -c -band
        x lapwso -c
        edit case.insp
        x spaghetti -so
I have appended the values of a certain band in the case.spaghetti_ene:

The strange is that if not conclude the spin-orbit coupling in spaghetti, that is "x spaghetti",then the band looks normal.
   Whether is it concerned with the E-parameter in case.in1?
   Did anyone else experience similar problems?

     Any suggestions will be much appreciated. Thank you in advance.
