Chaos Dungeon Resonance Bug

Today this has happened twice to me where my first run of chaos dungeons consumes all of my Aura of Resonance and then my second run is dropping infinite chaos mats. The first one was on the 1100 Punika Chaos dungeon, 2nd character was on 1370 Punika Chaos. Both of them only let me get rewards from 1 run and then I had no Aura of Resonance. Can this be looked into? In the meantime should I just not run Chaos in Punika as a caution to not lose materials by getting screwed out of the second run on the rest of my characters?
