When I configure pop-ups from my related table data in a webmap, I am limited by what I can show. The configuration window allows only one 'Statistic Operator' option for fields which are strings. 
A quick snapshot of the Service Directory shows that these are String fields.
How can I show these fields in a pop-up correctly, as strings, and not counts?
*This problem did not occur when I first uploaded and set up the pop-ups from related tables. The problem began after I updated the feature service by overwriting.
