Option set that does not return the value saved in the database, expression never turns blue

I have an option set that is saving an option in the database. However, I cannot display this default value as I have already tried using the expression in several ways and it never turns blue.

Why does it ask me for more expressions and operators if I just want to bring the value saved in the option set database?

I’ve tried searching for it and I can’t find the right expression.

Your Dropdown has a ‘Type of Choices’ defined as an Option Set (Tipo Morador).

Therefore, the Default Value MUST be a value of that Option Set (i.e. one of the Options from the Tipo Morador option set).

Currently you’re setting the default value to a ‘Text’.
