OmniFocus adds note when capturing reminder

I have OmniFocus set up to capture reminders created in Reminders.app on my iPhone 6 running iOS 9. Starting with iOS 9, the following text is added to the task's notes field: "Original task available in the 'Captured by OmniFocus' list in Reminders." This text is unnecessary. In fact, it's annoying, because it adds cruft to OmniFocus. How can I stop OmniFocus from adding this note?
