Dear all,

I have performed some calculations on a structure, the spacegroup (SG) of which 
is 62 (Pnma).
This spacegroup is also found by QE (confirmed using the verbosity ='high' flag 
in an scf run and running a thermo_pw.x to determine the SG and the special 
points in the reciprocal Brillouin zone).
When I did a phonon calculation, some modes did not have the correct symmetry:

For the SG 62, I expect 10 Ag + 5 B1g + 10 B2g + 5 B3g
However, what i got was: 10 Ag + 5 B1g  + 5 B2g + 10 B3g
which, if I am not mistaken, is a charactaeristic of the space group 53 (Pmna)

Anyone has an idea of what could be going wrong?
