This, unfortunately, is a known issue.
If you are alone, i.e., there is no more group left - just you, you are sometimes unable to loot the cache.
I make it a habit in my groups of asking everyone if they have theirs before I disband :)....or make sure I'm the last one to leave.
Also of note in that dungeon in particular, if someone dies and is running in - please don't loot the chest till they are back in the instance!
Thanks!
