Ah, well that definitely isn’t right. As you will see on my video, once the calibration is saved, I can open the set filters dialogue and then review or change all the information saved from the wizard.
Is it worth rolling back to an earlier version just to double check your particular configuration to see if the latest has introduced a bug?
Just to confirm that it definitely hasn’t saved any settings, you can duplicated your main profile, import the data from your filter wheel, to clear all the populated tables and then run the flats calibration wizard. You can then set up a test target with LRGB events, and then run the flats wizard, just to see if it does indeed populate the flats events. At least this way you will then be confident to report it as a bug.
