Missing points 6811 (R 0, C 947, G 5)?

[More_Fiber]

I downloaded the WU on 11/27 00:09 (UTC).
[19:25:15] Unit 9 finished with 96 percent of time to deadline remaining.
Log shows:
[19:25:38] + Results successfully sent
[19:25:38] + Number of Units Completed: 176

Extremeoverclocking shows 1 WU completed between 12pm and 3pm CT (18:00-21:00 UTC) but 0 points.

Can anyone explain a WU completed with no points?
