Conditional Values - Reference Fields

Erika,  I know that you are working on new forms and I'm more familiar with old forms so I will give you an old forms answer. Hopefully it's the same my new forms. You should be able to take note of the report which is used to drive that drop down. It will be a property of the form. It will either be the record picker report or an actual report. Regardless of which one it is when viewing a record in edit mode what will show up in that field is going to be the very first field on either the record pickers that you have selected in the advanced properties for the table or else it will be the first column of the report that you have designated to be used for the drop-down list. Check to make sure that is the correct field because perhaps it is showing a field which is blank on some records.
