When you pivot on Isotope Label, the "Transition Note" column is supposed to be pivoted, so that you would see the columns "light Transition Note" and "heavy Transition Note".
I am not sure why you are seeing the Transition Note where you are seeing it.
You might be able to fix this by choosing "Reports > Edit Report" and then uncheck and check again the "Pivot Replicate Name" and "Pivot Isotope Label" checkboxes in the Report Editor.
If you would like, you can send me your report definition and Skyline document.
In order to make it so that the Skyline document contains your report definition, you can go to:
Settings > Document Settings > Reports
and check the box next to "PeptideQuant_AllResults".
After you do that, you can do:
File > Share
to create a .zip file containing your Skyline document including that report definition.
Then you can upload that .zip file here:
