The data output from select columns in the dataset is not coming and because of this, I am not able to get suggestions in downstream clean missing data components. I am unable to debug why data output from select columns in dataset is not generating.
I had the same problem. However, it was still possible to view the column names with the "With rules" option. By clicking on the "enter column name" text box a list with all column names appears. You can select multiple columns in the same rule.
