Duplicate Page Bug

I just tried to duplicate a Page using the Manage Pages panel, but get the error message below  after I copy the page and click the "Apply" button.  The new page does not save after clicking apply.  This happens on my MacPro.  (I'm using the latest release of IB3.)

Thanks for looking into this.
