Attribute Weight with "?" Attribute

Hi,

When running a Decision Tree, in the Attribute Weights table, I am getting two lines, one with an attribute in my dataset, and another line with a "?" attribute.

Any idea about what this means and how I can solve it?

Thank you!

Hi @pedroomac,
for all we know, this looks like there is an attribute named "?" in your data set. If this is not the case, please share some more detail on how your data and process setup looks.
