The usual reason that chromatograms would be missing is that the Q1 and Q3 values of the SRM chromatograms in the .lcd file do not match the precursor m/z and product m/z of the transitions in your Skyline document.
The setting which controls how close those numbers have to be to each other is "Method match tolerance m/z" ("メソッド許容誤差m/z") at "Settings > Transition Settings > Instrument".
If you send us your Skyline document and your .lcd file we could tell you exactly 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.
The Share Document dialog in Skyline also gives you the option of including the raw (.lcd) files in the .zip.
Alternatively, you could send us that .lcd file separately.
Files which are less than 50MB can be attached to these support requests. You can always upload larger files here:
