Values in a form field are not showing in the preview or live form even though the value is in the picklist for the field. Visibibility rules for the field are enabled.
The value is not in the picklist in the field visibility rules. To fix this do the following:
1.Select the field in question in the form editor
2.Click "enabled" In the right pane, where it says Visibility Rules,
3. Add the missing value to the picklist
