I'm unclear what file you're exporting and where you're importing it.
I've exported PlatformPro settings from Dashboard > PageLines > Settings > Welcome (at the very bottom). You install Platform's exported file there too. PageLines Framework is not WP, so the posts are contained only in WP.
To export your posts, you go to Dashboard > Tools > Export and export all your content and WordPress settings (which are different from PageLines settings). To import the WP file in a different site or location, go to Dashboard > Tools > Import.
You should never see the messages you received when importing a WP file to WP, nor from importing a PageLines file into PageLines Framework. However, if you tried to import a PageLines export file into WordPress, it's likely they would show up.
