Vandal badge glitch

[Ukase]

I'm a bit stumped by this, as I've gotten this badge on three other characters. But for some reason, with my corruptor, I'm not able to see any progress. 

You can see from the picture - no progress shown, despite the system information clearly showing I've destroyed the items which should give progress. 

I am fairly certain I've satisfied these requirements, as the folks I was teamed with yesterday got the badge, but for whatever reason, I did not.

I should add, I just got this badge, it's only the progress meter that's glitched.

I believe that the Vandal Badge never has a progress bar, since it's monitoring a few different criteria.

Try running a few more Mayhems solo, and manually reviewing your combat log to make sure you're defeating the targets.  Do a tally and see if anything pops out.
