That's a multiValued variable, but I think that's a red herring.

In SCORE S. mansoni RCT the village variable also has lots of values and selecting all on that also causes a 500 error and zero count to show up in the Entity Diagram.

this is caused by the single-quote character in one of the values. there is an issue filed for that bug, so this issue is being closed as a duplicate. thanks though!
