i think John was expecting the files to say _r_a.xisf (for instance, if you ran SFS after alignment.) but from the screenshot i can see you have _a_c_cc_d_r.xisf.
i think since you are running a color camera, the right sequence should be:
calibrate, cosmetic correct, debayer, SFS, register, so _c_cc_d_a_r.xisf should be put into ImageIntegration. i don't think it makes sense to analyze an undebayered frame with SFS. also, it's certainly possible that one of calibration, cosmetic correction or debayering is not carrying the SSWEIGHT keyword forward.
