Dungeon Room Does Not Complete After Clearing All Enemies (Vaal Ruins)

I have encountered this issue three times today and once yesterday. The problem is that after I kill all the enemies in a dungeon room, the room does not complete, and I am forced to close the dungeon early and simply watch it get destroyed.

This is extremely frustrating and makes it impossible to progress in this content at all. I have also attached a video that clearly demonstrates the issue. Re-entering the dungeon does not fix the problem either.

Alright guys, now this is happening on every run. I literally cannot play anymore. This is really great.
