Successful third stage of Plague Star bounty turns failed after the end of the fourth stage

[(XBOX)DC COWBOY]

This is reproduceable on XBOX100% of the time.  On every run so far (20+) we will get a white dot after the third stage indicating a successful (non failed) stage because we completed the bonus objective.  After the fourth stage completes and the bounty ends, the reward screen shows a gold dot for the third stage indicating that we failed the bonus objective.  This is causing everyone to not get any of the bonus rewards for successfully completing all bonus objectives for each stage once the bounty is over.  With relics in the drop table, this is painful.
