When I configure export settings and try to save them as a new profile, not all parameters are saved. This differs, sometimes it doesn’t save the framerate, sometimes it doesn’t save the resolution, other times it doesn’t save the quality settings.
The easiest way to reproduce this is by setting the framerate to 59.940060. When I save it won’t save the framerate. Then, when I select another profile with a different framerate that was saved properly (say 30FPS), and switch back to my saved profile, the framerate will remain 30FPS and not go back to the 59.940060 that I saved.
