During the protomatter bomb shutdown sequence in the cave, Kuumaarke makes one announcement (via VO and mini-text) as she begins shutting down each pylon, and then another when the pylon shutdown is complete. However when she gets to Pylon Gamma and begins shutting that down, she announces that the pylon is already down:
She makes the same announcement a second time once Pylon Gamma actually is shut down (the second time around, it's correct). I presume that there's supposed to be a different Kuumaarke VO (and matching mini-text) when she first reaches Pylon Gamma.
