This issue is usually caused when the Expense Run hasn't been finished as the Complete Cheque Update has not been run. The Complete Cheque Update moves the status from Processed to Paid. If this is not run then trips will stay as Processed.
Check the Process Log
Go to Back Office, CoreExpense, Tools, Process Log
Search for the Expense Group and Week Number (Run Number)
Check for 'Update Submitted' and 'Complete Update' status
If these are missing then the Complete Cheque Update has not been run
Run the Complete Cheque Update
Go to Back Office, CoreExpense, Update, Complete Cheque Update
Enter Expense Group
Cheque Date, Current Run Number and New Run Number will auto populate
Check the Current Run Number is correct
Click OK
