I cannot tell from the pictures what is going wrong, but if you send us your Skyline document I am sure we will be able to figure out what is going on.

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:

Thank you for uploading your Skyline document.

It looks like the problem is that you have the "Explicit Retention Time Window" for these molecules set to 0.01 which is too small.
Skyline only looks for candidate peaks within that small window around the Explicit Retention Time, and when Skyline does not find any candidate peaks in that tiny window, and no peak gets chosen to be integrated.

You should go to:
View > Document Grid
and using the "Molecules" Report, set the Explicit Retention Time Window to a larger number (e.g. 1).

After you do that, you can tell Skyline to look for peaks again by going to:
Edit > Manage Results > Rescore

By the way, even if there are no peaks shown on the chromatogram, you can always select a completely new peak by clicking below the X-axis on the chromatogram and dragging the mouse across the range that you want to integrate. This technique of adjusting peak boundaries is mentioned on page 20 of the MS1 Full Scan Filtering tutorial:

Thanks, that solves it!
