Problem 1: We had the field-type "dropdown", so if the choosen value was "15" then in the Database the set value was {"31":"15"}.
Problem 2:
I have no idea how to fix that :(
Problem 3:
i think the field type is "short-answer", so we try to set a default value. But we could'nt find any way. but in code there is a value"" option. any idea?
