Some parking lot entries jump to today with increased procrastination count

Hello. I LOVE the concept of weekplan: being able to schedule all my tasks for the week in a snapshot view, and I love the functionality of the pending and parking lot lists. I'm having some trouble with the parking lot lists though.

Occasionally I find a couple of tasks from a Parking Lot list have copied to Today with an increased procrastination count. I haven't moved them and they haven't moved themselves - they appear in both a Parking Lot list as well as Today (duplicated), and their procrastination count has gone up. If I try to delete one of the duplicates it gets deleted from both lists.

There doesn't seem to be any logic to which ones copy and I'm afraid I'm not 100% sure how to recreate the error but it keeps happening so I thought I should mention it. Keep up the great work!
