Enumeration in microflow

Hello, For importing XLS I make microflows to correctly import the enumerations. I make an expression in the returntype.   As you can see, the last else I choose for Autmatische_Incasso. But.... Ik want it to be empty. Because I use an if/else expression, I need to add the last else. Otherwise it doensn't work. But what I want is that if it's not Autmatische_Incasso or Handmatig, the enumeration value should be empty.

You could just add "else empty" as the last line, that should fit your requirements.
