Kyveza ? Invoke the Shadows -- Clones not charging at same time

When I attempted the Kyveza ?? encounter earlier today, during the Invoke the Shadows shell game intermission, the clones were chaotically charging around the arena arbitrarily at different times. This happened nearly every time she used that mechanic. When I watched a video of the fight, it had all the clones charge at the same time, 12 times (which I assume is the intended behavior). I messed around with changing graphics settings, not using warlock curses, changing Brann curios, etc., but nothing helped. Would appreciate any advice on how to fix this. Thanks!
