[Building Sakai] Samigo problem with valid submissions getting 0 scores

[Karen Tsao]

Hi Tom,

I don't have any idea regarding your issue at this point. But can you
please check follow things for me?

For these students who got 0 points, do their answers exist? That is, can
you see their answers from grading pages? Can you also check if there are
multiple submissions for these students, from both UI and database.

Thanks,
Karen
