I'm on the 'Essential Elements' Quest Step. I was at 9/10 Materials Gathered and 96% Arc Ability Kills. I found the last Zeptocyte Core and finished off the Arc Ability Kills and my Quest Step is stuck. It says 100% and the bar is full but the box isn't marked. Really confused here? That's the best I can explain it right now, I wish I could post a picture on here.
