At times, NLP does not show the LUT selector on the second tab.
I get this with original files and with virtual copies as well as in Lr’s library and develop tabs.
Restarting Lightroom has not done any good.
The LUT and other settings I saved (when the LUT selector was still available) display correctly in the metadata.
Meanwhile, I found that he LUT selector only shows when “color” is selected - I wonder why.
Please note that LUTs are still selectable but irrelevant for b/w and “none” color model conversions.
