If you recently updated from an old version to V9.0n and your wall sheet/panel list creates the report, adds the table outline, but doesn't print the sheet list in the table, you will need to check the Setup > Preference Settings > Dimension Defaults and the dialog displayed may have values missing or lost during the update.
Check that all cells have a value in it, especially those indicated below, and select [OK]. We suggest that the appropriate text height be 2mm. This writes a new file RoofDef.csv to the..\User folder and the table should start printing sheet lengths again.
