Hi, Alex. I just noticed that nobody got back to you on this question. Sorry. If you have tasks that show up with the "ALL" filter but not with the "ACTIVE" filter, that means that the tasks are inactive. To determine if any task is active or not, and to learn the reason why an inactive task isn't active, check the "task info" display. On windows, it's in the right hand panel, in the section called "task statistics" at the tag "Action:" - I don't know the iphone but I'm pretty confident that this information is displayed somewhere in the iphone app.
The seven reasons why a task might be inactive are listed on page 41 of the User's Guide. Here's a copy of that section:
If Active is selected as the Action Filter then only Active tasks are placed in the list first and then other
filters can be used to select tasks from this list. To be placed on the list of Active actions, a task must
meet all criteria listed below:
1) the task must not have subtasks or these subtasks should be completed
2) the task must not have completed parent tasks
3) the Start Date for the task is not set or Start Date is now or in the past
4) the task must not have the option Folder checked
5) the task must not have the option Hide branch in To-Do List checked for this task as well as for any of
its parents
6) If one of the task's parents has the option Complete subtasks in order checked, this task must have
all above siblings completed to be placed in the list. Or these siblings can have Hide in To-Do option
set.
7) If the task has dependency tasks these dependency tasks must have been completed.
