[SOLVED]user-knn - Can't set attribute to role user identification

Hi,
I am building a recommender stream in rapid miner studio community version 7.0 and have come across a problem. The user-knn operator expects the example set to have an attribute with role "user identification" and another one with role "item identification". I have inserted the Set Role operator just before the user-Knn, however my target role drop down list for the Set Role operator does not have user/item identification roles. It only has {regular, id, lable, prediction, cluster, weight,batch}. I have rapid miner studio community edition 7.0 and recommenders extension 5.1.1.
How can I get round this?
Regards,
Walter
