I reported it 2 years ago (excerpt below). Although sometimes it gets fixed, it keeps coming back. It degrades workflow and creates a real risk of image loss. I am reporting it again in hopes of it getting appropriate attention AND BETTER TESTING.
Original post title: Lightroom CC 2015.6: pick/reject flags hit both images in Compare and Survey view
"When two images are being Compared, or are displayed in Survey mode, a pick or reject flag entered for the selected image gets applied to the second image as well. I originally observed this problem 'way back with LR4, possibly earlier, and have reported it before (long ago). After being fixed, it appears to be reintroduced with a major or minor release. It considerably degrades the process of tagging images to be discarded or worked on, and creates a real risk of desired images being discarded. ...why this simple problem keeps coming back is baffling, especially because it's so easy to test."
