Text for Delta potential in TreeADDs is a bit confusing

When presenting the text for a Delta potential in a TreeADD, the text shown is a bit confusing. For example, let us have the chance variable B, as child of a chance variable A, being A and B discrete. If the TreeADD potential of B is such as in a branch the potential for B is Delta with value absent, then the text "P(B) = absent" is a bit confusing. I would prefer to read the text "B = absent".
