I see that Skyline is showing you the Total Ion Current normalized values in the Peak Area graph.
If you want to see the unnormalized values you can right-click on the Peak Area graph and choose something else for "Normalized To >".
It might be that the reason that the values are blank for most of the replicates is that Skyline does not have a value for the Total Ion Current Area.
You can use the Document Grid to look at the Total Ion Current Area values for all of the result files.
If you would like to learn about the document grid you should look at the Custom Reports tutorial:
There are many reasons that Skyline might not have a Total Ion Current for a replicate. If you send me your Skyline document and raw files, I could figure out what happened.
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 and your raw files are less than 50MB you can attach them to this support request.
You can upload larger files here:
