Why Is JanusGraph Not Clearing Old KeyColumn Claims?

[ZachMurray]

How do I get rid of these KeyColumn warnings?
JanusGraph spits out an endless flurry of discarding expired-KeyColumn-claims
As I cleanup my JanusGraph with a while-loop of g.V().limit(10000).drop().iterate();

[WARN] [o.j.d.l.c.ConsistentKeyLocker.main] ::   Discarded expired claim on KeyColumn [k=0x0xD8000000003FDD80, c=0x0x24] with timestamp 

1. What is going with these multi-day-old expired-KeyColumn-claims?
2. Can I fix and or cleanup these?
3. If not. how can I hide them while keeping the rest of the logging?
