Problem with Wraeclast besieged

Hello,

I ran a Caldera map with a level 6 map, and tested Wraeclast Besieged, and another Breach Percusor tablet. While I cleared the map and killed every monster on it, the breaches failed to close. I have ran across the entire map several times, looking for hidden monsters, left-reentred instance several times, tried logging out and restarting the game.

Map shows zero monsters remaining, all map content is tagged as completed, as well as the map itself, but breaches do not close, so no lovely, lovely rewards for me today.

I know it's early access, so it's not a big deal, but reporting it non-the less.
