iWork saved state

I cannot find com.apple.iwork.savedstate to disactivate Resume. Pages, Numbers & Keynote keep opening last files, a whole lot of them, and I cannot disactivate this feature. I have already unticked Restore windows when quitting and re-opening apps.
Any way to keep this permanently from happening ?

Have you restarted the machine since unticking the box in "General"?

Have you repaired permissions lately?

Repaired permissions now, had already restarted machine since unpicking box, even tried Application State Cleaner app which by the way does not have in the list the iWork apps. The other apps are fine, it´s just the iWork. Continues the same.
