LrC 15.3 Rating broken

Since the update, rating is lagging to infinity. I never know if it will rate an image or not.

Did some testing, when pressing 7 times for example 1 on the keyboard, it jump every time to the next image, like it is rated, but no star appears, then like 20secs later, it shows the stars. undoing the rating by pressing 0, same effect.

Or other behaviour, it will rate it immediatly, but now show the star it seems, when going click back on the image, it will update the start. No while typing this doing experiments. now unrating with 0 doesnt work (it does show on screen that it set rating to zero) but the star remains.

This is unworkable!
