Flat field correction decides to use different callibration frame mid batch

[Alexawka]

Hello,

• Version of the app - 12.0.1
• Windows 10
• Basic steps to reproduce the problem:

1. I have series of photos and a calibration frame. Calibration frame is last in the library as per manual.

Here is the screenshot before Flat Field Correction

2. Now I select all the photos and perform Flat Field Correction

• Expected result - all pictures are corrected
• Actual result - frame 9 is not converted to DNG (Stays RW2 on the screenshot) and all subsequent frames are corrected based of this frame for some reason - you can see green colorcast after this frame that coincides with darker area of the image

4. If I try to Flat field correct this single image:

• Expected result - One selected image converted
• Actual reult - nothing happens - DNG is not created.

My hunch is that it is considered as calibration frame as well for some reason.

Please advice

I am having the same issue. It seems like LR wants to have 1 calibration frame per image. If you were to cmd+select the calibration frame and a single photo, it would work perfectly. 

I'm not sure if there's a way around it - I really hope so because this is pretty annoying to do.
