WvW Silverwastes reward track shows wrong reward box

It seems the Silverwastes Reward Track in WvW drops a Warclaw Armor Box. I haven't finished the reward track so I don't know which will drop. I have already finished the warclaw track and have put points into the mastery on that character. The screenshot is from 10.3. but it was still the same yesterday evening.

Same in the PvP reward track. :/

By the way, the final chest was indeed the warclaw chest -- it's not only a visual problem.
