Either you have mis-generated your input qpoints for the band structure plotting (list 1) or you are getting aliasing in the Fourier transform interpolation of the band structure. This usually happens near Gamma, and if your compound is fairly well behaved and your qpoint grid dense enough it shouldn't be the problem.
