Hi there,
I tried to do something similar to your picture and it seems to work for me.
When I defined the attributes of my requirement type, I had to select “Attribute Definition Enumeration” for the attribute I wanted to have enumerated value (so the Status in your case), instead of just “Attribute Definition”. That way, only the enumerated types were available in the selection wizard.
Did you also do like this?
Otherwise, when I try with “Attribute Definition”, I get the same behavior as you.
So, I hope this answers your question.
