Check the following settings:
Settings > Betting Options > Banking > all unticked
Settings > Betting Options > Triggers > No triggering till unticked
Settings > Monitoring Options > Start monitoring x before beginning ticked
Settings > Monitoring Options > Idle and inplay refresh rates 1 sec
Settings > Test Mode > Delay placing... unticked
What distance race did you test on. If 5f it will trigger around 30s in.
