Problem with "Underlying Value" = untitled

Welcome to the community, @Ricardo! When you get a chance, please introduce yourself here.

I'm very sorry to say, but there is no way to find out the "English" answer.

As to why this happened, this is a little subtle because having non-unique underlying values is allowed. This is needed when you want enumerators to see language that is familiar to them, but want the underlying data to be the same for easier analysis. In the example below, violet and purple are different choices, but they have the same value of 2.

label value
brown 1
purple 2
yellow 3
violet 2

While this is a useful technical, when it happens, it's likely a form design mistake and we should warn form designers. I've filed an issue at https://github.com/opendatakit/build/issues/224 so we don't forget to make this change in Build.
