Can you send us your Skyline document?
In Skyline you can use the menu item:
File > Share
to create a .zip file containing your Skyline document and supporting files including extracted chromatograms.
If that .zip file is less than 50MB you can attach it to this support request. You can upload larger files here:
The usual reason that ratios like that do not show up is that there is no molecule which has a heavy and light precursor. That is, the heavy and light precursors ended up in separate molecules.
There are four levels of things in the Targets tree: Molecule List, Molecule, Precursor and Transition.
In order for ratios to be calculated by Skyline, there needs to be a heavy and light Precursor which both have the same Molecule parent.
It's also possible that something entirely different is going wrong. We will be able to figure it out when we see your Skyline document.
