Something that has been reported, but never fixed, was the way the NASB would attach notes to the heading above a verse rather than the verse itself. This has been showing up on the iPad app as duplicate notes in different places. To duplicate, go to Hebrews 1:1 or Revelation 1:1 and make a note in the NASB on your desktop. Then open the iPad to that verse in the NIV84 and you should see two identical notes. You may have to reboot the iPad to force it to sync. If anyone can verify this behavior I will change the title to "bug". Thanks!
