I do not know why things would look that way but if you send us your Skyline document I could figure it out.
In Skyline you can use the menu item:
File > Share
to create a .zip containing your Skyline document and supporting files including extracted chromatograms.
Files which are less than 50MB can be attached to these support request. You can always upload larger files here:
https://skyline.ms/files.url
Usually with a bug like this the problem turns out to be that there is one item in the list that is messing everything up. That is, Skyline is trying to display an average value and there is a single infinity in there that causes nothing to be able to be displayed.
After I see your Skyline document I will probably be able to figure out what is going wrong.
