check if you have libfft-devel installed.

else some filters do not works in image editor as they requires layers
from host application as Krita or Gimp. digiKam IE do not support
layers. I don't find yet a way to disabled the filters requiring
layers in GMIC-Qt.

Don't forget also that filters are script which can be under
development and can be updated via Internet. So i recommend to always
use stable filters in production.
