Missing Value node is not removing missing values, What is the fix?

Hello guys, hope you’re all well.

I have a data set, where per the description of the dataset, the “?” key is an indiciation of a missing value.

This is where I got my dataset from: https://archive.ics.uci.edu/ml/machine-learning-databases/breast-cancer-wisconsin/breast-cancer-wisconsin.data

And this is a description of the data set:

https://archive.ics.uci.edu/ml/machine-learning-databases/breast-cancer-wisconsin/breast-cancer-wisconsin.names

The way I’m trying to remove the missing values is as follow:

I use the file reader to read the URL I add the Missing Value Node, I configure it as follow:

Number (integer) : Replace with Mean

Missing String: Remove Row

This is how the workflow looks like:

However, when I view the table, I still find rows having missing values:

I’m assuming that knime is not viewing the ? as missing values, but what is the solution then?

Thank you!
