We are working on a survey where we are using choice filters as cascading selections with the following field order:
Zona > Sector Municipal > Estación
As expected, the Zona field determines the list that appears under Sector Municipal. However, after a Sector Municipal is chosen, no data is shown for the Estación field. The following image shows sample data where, indeed, there is data under the Estación field.

However, when we look at the survey for the Número de Orden entry ending in 07191, we see the Estación field is not behaving as expected.

We have seen that when changing the Sector Municipal to another choice on the list, and then back to the original choice (back to 801 in this case), then the Estación field behaves as expected and shows the correct choice.
I'm including the Excel used to prepare this survey. Any help would be greatly appreciated.
