Unexpected behaviour switching between clip grading and tim

In Resolve 15, when i switch from timeline grading to clip grading, the grading also switch. I mean that the image change only by switchig. When i'm in clip grading, i don't see the result of my timeline grade. For example if, in my timeline, i've set my saturation to 0, if i switch to clip grading, all my saturation is back. How can i work with that? What am i missing? That was not the behaviour in Resolve 14.

Check and see if Highlight Mode is turned on, or if either Timeline or Clip Node mode is bypassed.
