Color Still problem...
 

I've got some problems with the still store...
I've opened a projects from FCP, no grading applied (yet).

When I open the still store and create a still from a clip (the reference clip to CC all the others), load and show the still wiothout moving the playhead (so the still is identical to the clip frame) the waveform scopes shows me different waves. Why is that? Nothing changed in Color, just opened it and created the still.
