Your diagram is wrong.

 

But the advanced bot simulates and bids 5♦ almost every time for me, so seems to be working as expected.

 

(Usual stuff about why it may not do that every time etc - always need to focus on the most common bid, rather than a unique data point. Makes no difference on most hands since it finds that the opps almost always bid and make 5♠.)
