Invoice line context sensitive DFF on interface lines and trx lines, values on trx lines no show

Summary: I have defined context sensitive descriptive flexfields on ra interface lines and ra customer trx lines. Once the external invoices have been imported I can view the values populated in ra_interface_lines, but not the values on ra_customer_trx_lines. Values for both DFFs are populated in the table ra_customer_trx_lines_all. The DFF segment names on ra_customer_trx_lines are visible, but not the actual values. Any idea why the DFF values for ra_customer_trx_lines are not appearing in the UI?
