Well, actually I checked again and somehow those two paths got reverted to (None), probably me testing around being the case. I changed it back to “Settings/profiles” and voila… it works.
But this introduces a new problem. As I have to use “(Dynamic)” for “Default Processing Profile” in “Preferences->Image Processing” all photos that I don’t make a Dynamic Profile Rule for will not be applied with “Auto-Matched Curve - ISO Low” as I normally have adjusted.
The software rather should have a setting where I can adjust which Default Processing Profile should be used for images that don’t have a relevant Dynamic Profile Rule.
