Running Collections Strategies

Hi,

We have been testing the Collections Strategies and have noticed that if we create an invoice that is overdue by 60 days, the strategy works fine up to 60 days which is when I would expect the strategy to stop until the next task date is hit. Unfortunately the strategy continues to the end of all the tasks in excess of 60 days (i.e. all the tasks up to 100 days over due).

Has anyone experienced this or can give some ideas on how to fix the issue.

Thanks

Jon
