[Wien] K-point not treated with irrep when calculating band structure

[王静]

Hi! everyone,
When I am calculating bands structure, the following tips appear after "x spaghetti -up": 

number of k-points read in case.vector=          51
 k-point nr            1  not treated with irrep
 k-point nr           31  not treated with irrep
 k-point nr           32  not treated with irrep
 k-point nr           33  not treated with irrep
 k-point nr           34  not treated with irrep
 k-point nr           35  not treated with irrep
 k-point nr           36  not treated with irrep
 k-point nr           37  not treated with irrep
 k-point nr           38  not treated with irrep
 k-point nr           39  not treated with irrep
 k-point nr           40  not treated with irrep
 k-point nr           41  not treated with irrep

SPAGH END

Is there something wrong with the .klist_band file? or others? 
Could anyone help? Thanks in advance!
