Toodledo sync but don't show sub task as sub task

When I sync Organiser with Toodledo, all the task are transfer flat. The sub task are not sync as sub task. The other way around, toodledo to organiser it work perfectly. I have to manualy move task in Toodledo to get sub task the way it should be.

I like very much the apps. I did work with it for only a couple of hours and its great. Minor bug or my mistake or misunderstanding, for the sub task.

Let me know.
