"Loop Labels removing label"
Hello I am working with a dataset with polynominal data. Using nominal to binominal I generated 4 attributes for the original label attribute. I would like to create models for each of these label attributes. I referenced the 'loop labels' documentation, used set role to set one to 'label' and the rest to 'label2', 'label3', and so on. After dragging exa to 'loop labels' with my sub process inside, I get the message "input example set must have special attribute label". This is weird because I have set the roles of 4 attributes as label. Checking the focus inside the loop labels operator, I discover that the attribute I designated as 'label' is missing and the other three (label2, label3, label4) remain. Help would be appreciated. I have inserted images illustrating this issue.
All labels have been setInside loop labels, label has been removed
Edit: I would also like to point out that the built in tutorial for 'loop labels' also experiences this error.
