Ed,
Did you check side clearances in the apex groove before assembly?

Second set of photos
 
Photo Apex Scrapes shows that the ejected apex seal piece probably  made it around the chamber a couple of times, one impression looks to be smaller than the width of the ejected piece - so perhaps it broke up further in its round.
 
Photo Apex Slot Peened shows that the 2nd apex seal of #1 rotor that would not move up and down - clear why, now.  The departing piece peened over the slot and froze the seal in its slot.  I had to pry the opposite end of the seal up to the position you see.
