[Pw_forum] B3LYP and fhi2upf.x

Dear QS users
I want to use B3LYP which is hybrid functional. As I saw in the mailing list, I have to consider two points 

1- using input_dft='B3LYP' in the &system 

2 - using norm-conserving PPs. 

But the problem is that QE don't have any norm-conserving PPs for Cu, Ca, and O. Therefore I tried to use fhi2upf.x for converting Abinit PPs to QE. I did following steps and finally the program give me PP while several parameters are zero in the PPs such as Rcut, Rcut US, and E pseu. Furthermore, I couldn't use it in the calculation.    
I attached several lines of PPs for Cu 


Is it Ok or wrong?
Best wishes
Ali
