It bothers me. However, you don't have to reconcile ALL of your Jun, Jul expenses, just the ones that are in the system at the time you submit. It's a pain.
The system used to tie an expense to the report. Now all the expenses (airline tickets, airline tickets canceled, credit card charges) that are in FOX have to be tied to a trip (entered by you) regardless of the month you want to submit. I guess it prevents you from forgetting an expense when you submit the report.
I'm having to keep 3 reports open at a time (previous month I'm ready to submit, last month, current month), since the expenses and tickets in FOX span 3 months.
