Color cast with Sigma X3F files

I am a new user, and very impressed with XnView's functionality.
I'm experiencing a strong green color cast in the rendering of Sigma X3F images (but not with Canon or Olympus RAW files) in the Brower Preview pane - and not in the case of the Thumbnails, nor in Viewer Mode. Is this normal?

I attach a screen print that illustrates the problem.

Hmm, I have little experience with RAW files, so I'm just guessing:
Choose menu "Tools > Options", category "General > Read/Write", tab "Read" to open options for reading and displaying various file formats. Please make sure that the values for Red Scaling and Blue scaling are 1.000. Try unchecking "Use camera white balance" and see what happens when displaying your greenish images.

Thank you for the response, Helmut.
I have followed your suggestion, and checked that both Red Scaling and Blue scaling are 1.000. And I've tried all four combinations of Camera White Balance and Automatic White Balance being on and off, but there is no visible change, regardless of the white balance settings.

It's known issue with X3F (and dcraw), currently only the embedded jpeg can be viewed correctly
