HLG Color adjustments not showing in Comparison Viewer

I'm experimenting with HLG via two different Panasonic cameras (both shooting 10 bit .mov PR422 - ALL frames). FCP 11.2.

I noticed that when I save a timeline image in the Comparison Viewer, the color adjustments are missing.

They show when I click the 'Timeline' tab (in Comp Viewer) but I can't see a way to save that. When I click the 'Saved' tab and save the image, it reverts to the muddy version.

Any learned advice will be very welcome!

(I attempted to edit the above but it wouldn't save, so I copied the text and then deleted the original text. When I pasted the saved text into the post, and clicked save, I found the system had created two copies (even though I didn't click any reply button).

Ahhh...

I initially suspected the reason for the uncorrected version of the clip showing in the Comparison Viewer was because (in my haste) I had colour corrected the clips in their own timeline, rather than a project timeline, but on checking, I found that saving the frame from a timeline made no difference.
