Error in routine epw_readin (1): You should define either filkf or nkf when band_plot = .true.

Hello EPW users and developers,

I am getting this error:
Error in routine epw_readin (1):
You should define either filkf or nkf when band_plot = .true.

regardless of specifying filkf. I have filkf in the same working directory but it still complaining about filkf?

Here is my input:

Hi Rijan,

As the error says, you should define either "filkf" or nkf" and not both as you have in your input file.

Best,
