Hi eagle3y3507,
I'm sorry to hear that was the case.
To help us look into this further, if you haven't already, please speak with the Support team through one of the channels below:
Was the Sharpshooter run your second attempt with the same Character?
If so you weren't rewarded as you only earn rewards on your first successful attempt each week.
If however the Sharpshooter run was with a different save slot, this is definitely a bug going by all the information given about the raids by Ubisoft.
