Bug With Fiji Film Emulation Display vs. FP Settings

DxO FilmPack macOS topics
1

I opened standalone FP 6.2.0.252 on macOS 11.6.5 on iMac 2019 and found that

  1. at default settings, the emulation is applied on RAF files (expected)
  2. when I switch off the use of film emulation, the emulation is not applied (expected)
  3. when I revert to default settings, display is as in step 1
  4. when I repeat step 2, emulations are turned off, except for the first image.

What is the “official” way to remedy this situation?
