This isn't a problem, it's a way to make sure drop tables don't become over saturated.

If all currently vaulted items were in today's reward tables it would dilute the other rewards. Eventually there would be a point where every reward would have an incredibly small chance to drop due to numerous other possible drops. Retiring old items ensures players have a decent chance to gain new ones.
