It turns out there is a really messed up row in the "Blood Draws" table. Go here

https://test-ehr.primate.wisc.edu:8443/labkey/query/WNPRC/EHR/executeQuery.view?query.Id~eq=r95061&query.queryName=Blood%20Draws&query.sort=-date%2C-quantity&schemaName=study&query.ignoreFilter=1

And you'll see the row right at the top. I didn't see the row initially because the default view has a filter on QCState, and this row has QCState="In Progress"
