Trial balance report filter not working

Hello,

The date filter on my trial balance report has stopped working. When I input a date range the report gives me the total for the whole period. Please help me. I am using Navision 2009. The filter was working before. Just before this issue occured I had made a few changes to my COA (I changed the account type for a few COAs and added a new COA).

Thank you,

Teena
