Sage Timeslips 2011 LEDES - Export Error

This is my first time exporting a bill into LEDES format. I have entered all L, E, and A codes and have double checked for missing fields, but still when I try to export into LEDES the error message "Expenses do not contain litigation codes" pops up. I'm running out of ideas, and since I'm using Sage Timeslips 2011, I no longer have Support Help.

Please someone let me know what I can do! Thanks!
