[Wannier] Too many projections defined error

Hi, I'm having an issue that I'm very confused about.  I'm running a
calculation on silicon with 12 atoms per unit cell.  There is a gap in my
system (pwSCF tells me that 7.3 is the highest occupied state and 8.4 is the
lowest unoccupied state).  I just care about the valence bands and so I set
my upper energy window to 7.8 eV and set num_wann=24 (num_bands=32).  My
frozen energy window is the same as my larger window and it covers all 24
valence bands.  However, when I run the wannier code to generate the .nnkp
file it tells me the following error:

 param_get_projection: too many projections defined



Any help in understanding why this is would be greatly appreciated!

Best,
Brad
