Description
When creating a composite locator some input fields from the participating locators were removed in the Field Map parameter. Every participating locator's input field must be mapped to a composite locator input field. Removing input fields from the participating locators will create an invalid composite locator that will cause geocoding a table to return unmatched results. This also affects composite locators published as geocode services.
Solution
Ensure that all fields from the participating locators are included in the Field Map parameter. If input fields were removed, click the Reset button 
to add them back as input fields.
