How to remove "?" sign in a decision tree?

Hi,

I have created a decision tree using a decision tree and optimization operators; however, it shows "?" sign in the decision tree. How can I get rid of it or its better interpretation?

Thanks

    Hi,

    it's usually indicating a missing value. So you should avoid to add missings.
