LR has started to rate all photos (current and previous, from multiple cameras) as 5 stars. Problem persists after reinstallation of LR, and resetting preferences to default. Often resolved by closing and restarting LR, but re occurs. Running Sierra OS 10.12. Has anyone else seen this issue?
Please check that you're not using any preset while importing the images into Lightroom.
Also, update the Lightroom to 6.9/2015.9 version.
Thanks for your prompt reply Mohit. I am not using any import presets, and the LR version is current:
CC 2015.9, Camera Raw 9.9
