APP won't apply my matching dark flats to my flats, says I have to have a bias or matching dark flats. I took my dark flats at the same time as my flats and with the same gain, temperature and exposure lengths. Here's the message

CRITICAL WARNING: flat-field calibration can not be performed correctly!

To be able to perform accurate flat-field calibration,
the provided flats need to be calibrated by either

- a MasterBias, of the same ISO/gain value as the flat frame, or
- a MasterDarkFlat of the same ISO/gain value and the same exposure time as the flat frame, or
- both
