The resources tab of ES3 Workbench is not getting updated with the recent xdp files after migrating ES LCA into ES3 Workbench. May I know the reason for this?

We are using Adobe Livecycle Designer ES3 version. We have created two different pages in a form having repeat instance functionality, and also we have bound these two pages to the same XSD element. But the PDF data are not saved though the reader extension is applied. Please suggest us on resolving this issue.Note: The instances are also not repeating as expected.Thank you!Regards,Lakshmi
