Display Unique ID widget on form

Alguien sabe porque no me aparece visible el campo de Unique ID en mi formulario.? lo agrego y veo que todo esta bien.. pero no lo logro hacer visible al momento de nuevos envios.

Unfortunately, Unique ID widget is always hidden on your form. There is no current option that will enable you to display the Unique ID field on the form. Unique ID is generated upon submission which is the reason why this is always hidden. The Unique ID field upon load of the form is set to empty. Once the user clicks submits, the Unique ID will be generated. This logic is implemented to avoid gaps between the unique IDs generated.

For example, if three people load the form and it shows them UID_1, UID_2 and UID_3 and then the second person does not complete the form, there will be a gap in the ids.

If you want your user to see the generated Unique ID, you can add the field to your Thank You page.

Once user submitted the form they will see the Unique ID generated at the Thank You page. 

Genial.!!! EXCELENTE APORTE. ya lo cambie.

Muchas Gracias.
