Hi, Anthony. Without seeing the rest of your profile I can only guess. Here's one guess. Low importance (or urgency) for a task doesn't say that the task is unimportant. It says that the task isnt important to the completion of its parent. If the parent for some reason is highly important that might in some circumstances offset the low importance of the subtask.
Do you think you could set up a test profile with all of your sensiive or private information stripped out, but that still showed this problem? If so pkease send it to the forum so someone can have a look
