OK, well, the flat looks reasonably normal, if not a bit mishaped, and the uncalibrated light looks like a fair match. The calibrated light looks sort of "over calibrated"". Ive seen a similar situation before, with a missmatch between light and flat filters. Are you absolutely sure the light and flat filters are the same?, check the filter allocation is correct in DL set up, or there isnt a mix up after capture. Check the FITs header filter data for each, DL auto calibrate relies on correct fits header data. Try manual flat selection for a light to confirm.
