When you select multiple .MXF files from a Sony FX6 that were shot in SLOG3 and right click - Interpret Footage -> color space override is grayed out. It only works if you override one clip at a time. This isn't always the case and the bug seems to come and go. The bug might only happen when there is a mismatch between clip settings.
For professional use, the fact that a LUT is automatically applied drives me nuts. It's not the LUT I will ever use. It takes multiple clicks to override this auto-applied LUT and as I have noted above, it doesn't always work.
A similar bug I should include in here is that if I share a project with an editor and then re-open it and relink media, the LUT is again auto-applied to the clips so I have to go back AGAIN and remove it. The program should remember my preference to override the color space back to rec.709.
