Show unique entire in dropdown

Hello,

I hope this email finds you well.

I am reaching out to seek your assistance with an issue we are experiencing.

Details of the issue:
We have configured two forms as follows:

1. Form1 contains a single field for selecting a “Country.”

2. Form2 includes two fields:
A “Country” dropdown field dynamically populated from Form1.
A “City” field where users can manually add cities.

The issue:
After adding a few cities in Form2, we noticed that the “Country” dropdown menu in Form2 begins to display duplicate country entries. This redundancy creates confusion for users and impacts the usability of the form.

What we need:
I’m looking for a way to ensure the “Country” dropdown menu in Form2 only displays unique countries, regardless of how many cities are added.

If there are specific steps, settings, or adjustments required to achieve this, please let me know. Your guidance will be greatly appreciated.

Thank you in advance for your support.

Regards,
Richard
