Copy/Paste Settings stopped working

I’m on M1 Mac OSX 14.2 using NLP v3.0.2 and Lightroom 13.0.1 and try to copy setting (Brightness, Temp, Tint) across multiple photos. The Copy Settings window appears when I copy, but nothing happens when I try to Paste on a different photo. It’s only sometimes, and I have been able to see a pattern. Does not help to restart Lightroom. Other suggestions?

If you are trying to sync settings across multiple photos in Lightroom, have a look at the instructions provided here:
