Unique field IDs

I have two active forms which have a personal info stage which asks for user’s first name, last name, email etc. Now feathery doesn’t allow me to use the same field IDs for example “first_name”, even though it’s a different form where I am using the same field id. Am I doing something wrong or is it supposed to behave like this?

From my experience that’s by design, you’re allowed to use the same field data by naming the fields the same. In my form, I had to add a suffix to the field names if I wanted have a duplicate form with it’s own field data. I just used an _ and a number.

Yes, the field IDs are unique across your forms. This is by design.
