Custom Projects missing after Test MTP

We are in middle of performing application upgrade from HRMS 9.0 to HRMS 9.2

While recently doing a Test MTP pass, all the custom object definitions were migrated from source to target but associated project definitions weren't copied. When I looked at MVPRDEXP.DMS found out that tables that stores project related information were exporting only the PeopleTools projects not the custom projects. Below are the EXPORT stmts.

-- PEOPLETOOLS PROJECTS

EXPORT PSPROJECTDEFN WHERE PROJECTNAME LIKE 'PPL%' or PROJECTNAME LIKE 'PT84%';

EXPORT PSPROJECTITEM WHERE PROJECTNAME LIKE 'PPL%' or PROJECTNAME LIKE 'PT84%';

EXPORT PSPROJDEFNLANG WHERE PROJECTNAME LIKE 'PPL%' or PROJECTNAME LIKE 'PT84%';
