A RapidMiner user wants to know the answer to this question: "Hey there, I'm using the latest version of RM and I had an old process which involved the "Correlation Matrix" operator previously I could see the correlation matrix normally but now, I see a lot of "?"/NaN values for the resulting matrix"

Correlation matrix shows "?" if the attributes are non-numericals like text. Can you ask the user to check if attributes are numerical?
We can deep dive if the user could provide XML or Data2
