We are fairly certain we have identified a bug in the EXB query widget. For a field that contains specific word that is capitalized in some records and not in other records, a query will return all results (both capitalized and not capitalized) in the table, but the graphics representing the same result that gets drawn on the map only show records that exactly match the case of the input query string. In other words, the query statement result in the results table does not match feature display on map for the query result. This is happening on a hosted feature layer in ArcGIS Online. The attachment clearly shows this issue, which can be replicated with other hosted feature layers.
