It's all going grey

Anyone else experienced this? RGB images taken with a QHY8 in Nebulosity. Nebulosity displays the images in colour both as taken and subsequently, if you choose "display image" and pull one from where it has been previously saved.
Then, last night, I decided to do some new flats and merrily recorded away, images displaying colour (I was doing flats for my hyperstar so doing twilight-sky flats). But then, when I try to stack the lights with the flats, the flats show up as being in greyscale. And I see now, that loading the same light images into MaximDL (4) shows them as greyscale.
What's happening?

I was under the impression thats flats were converted to B&W as you are only interested in the luminence values anyway

Flats get turned into greyscale as previously noted.

Have you got Neb set to automatically debayer?

I save the raw FITS images. Apart from anything else they are one third the size.

I then apply the flats to the lights, debayer after that, then move on to stacking.

All noted but the problem is that DSS won't recognise the flats. It throws up an error message saying there's a mis-match in size, shape, depth etc - trouble is, there isn't anything except that the fats are listed in the "Open files" list as greyscale 16 Bit whereas the lights are RGB 16 Bit. So how the dickens do I force DSS to play ball? I never had this problem before and while I will happily recognise that it's all my own stupid mistake somehow, I just can't see what I'm doing different.
