You should see a small box that opens in the middle of the screen with a few options. The default pattern option is pulled from the fits header. Then select OK. Up to 4 new 1/4 images will be created.

I see it now. It only comes when keyword BAYERPAT is available. Not when it is missing as in my test files.

I have added a BAYERPAT kewword in my test file and tested with RGGB. Then green is black in the green extract. So it looks like red and blue are swapped with green green.
