In Curves tab in QU, I have a Saved RGB filter curve for linearizing a paper's tones for B&W.

I also made a small change in the RED Curve with it to correct some color I saw creeping in.

I'd like to move the RED curve back to its linear-line Default setting and try something else there in the RED curve.  However, when I hit Delete it erases the entire RGB curve as well as the RED curve (  ).   I'd like to keep the RGB curve but it goes bye-bye too (which becomes a big pain to redo.).

How can I keep the RGB curve, while deleting some other curve in the Saved Curves filter?

Tia.

Thanks Fred.  Seems easy enough.

I should have remembered the IN and OUT boxes are the same initially, just I am altering the curves so much lately they look odd.

Fwiw, some odd curves showing up.  PS is blocking up the blacks badly in 21 step wedges, and even the calibrators are doing it albeit somewhat better tonality than stock paper profiles.

Image is of the "Inkpress Cold Press 300" RGB curve I used to make it linear in QU, and the less red ink needed (red curve) in the shadows as well.  Still needs some mid-range tuning in the wedge for a green bit.  The paper may be a warm tone hence the red in the shadows, but it doesn't say on the box.
