I had a similar problem and follow the below steps it will work. 1. As mentioned above k-point weight. 2. After SCF , you have to do the keyword 'band' calculations. Looks like you are plotting band structure after nscf, without running 'band' calculations.
3. Then do the bands.x calculations to plot the band structure using gnuplot or plotband.x. Hope it will help you.
