Dashboards can be configured to display many different types of Views. One possible View is a Multi-Page View.

When exporting a Dashboard that contains Views with multiple pages, not all pages are in the PDF. Why?

Is there a way to resolve that to export all data for that View?

All supported CA Performance Management releases

What has been observed in the PDF export is expected functionality. All Multi-Page Views within a Dashboard exported to PDF will show the same behavior.

That Documentation has the following statements related to this scenario. 

When creating PDF of a Dashboard "on-demand" it states:

"Export a dashboard to a static report in PDF format. The PDF includes only the information currently visible in your dashboard."When emailing/scheduling a PDF run it states:

"For First Page, only the first page is attached and sent in an email message. For All Pages, an email message is sent with a time-sensitive link to the report containing all pages"
