Very confusing

The way this application syncs with iphone reminders is completely obtuse. Ive had so many instances of lists duplicating/deleting that I have no desire to use it anymore. Yet the settings and options make no mention of this, so I cant diagnose whats going on. Ive just gone back to the default notes app since this one is no longer simple nor predictable.
