Encountered error in module CreatCalibrationDetails APP 1.083-Beta2

Here is the console log.

@rysudo Can you tell us more about the data? Did you use raw calibration files or previously created masters? If the latter, does this also happen when you use the raw calibration files? And if you are using a master, what version of APP did you create it with?

@wvreeven Thank you for noticing me.

I'm not using master calibration files on this case.

- All files are raw calibration files. 30 lights, 30 darks, 30 flats and 30 darkflats.

- APP 1.0.83 Beta2 

My camera is ZWO ASI294MCP (OSC) . I had never experience "java.lang.NullPointerException" error with other several nebula files before.

I guess it is data dependent ?  

This data is short (5sec) exposure of M42 nebula.

Thanks,
