Reproduction Steps:

1. Go to Control Panel > Sites > Page Templates
2. Create a Template called 'My Template'
3. Go to Site > Navigation > Public Pages and click add a Public Page
4. For Type, choose Templates > My Template then add the page
5. Go to Site > Publishing > Export and create a custom export
6. Make sure the page you created is selected for export and Export
7. Download the export
8. Delete the page you created and then delete the template you created (alternatively you could use a different bundle)
9. Go to Site > Publishing > Import and select the Export you downloaded

Expected Result: An error is displayed using the language value, something like "The lar file could not be imported [...]"

Actual Result: The error is displayed but it displays the language key "the-lar-file-could-not-be-imported-because-it-requires-page-templates-or-site-templates-that-could-not-be-found.-please-import-the-following-templates-manually"
