Missing attributes

Hello,
I am having the classical missing attributes problem. I have three nominal attributes, and I want to turn two into numerical, and one into text. When I use nominal to numerical only the attribute I want to turn in to text shows up. I tried the "synchronize meta data with real data" to no avail: the attributes do appear after I select this option, but then RM converts each entry into a new attribute.
Any help is appreciated.
Best,
Bernardo

When you are transposing the data, you are also transposing the cluster column which has nominal values cluster 1 and 2 for the other columns, that is causing the issue. I dropped it and the flow works as expected.

thank you very much for your reply! Your suggestion solved the problem. What upsets me is that I was aware of the problem, and cleaned cluster using filter examples. It did not work.
Even when I reproduced your solution the attributes would not appear, and I used inverse selection to save the day. There is something weird with RapidMiner regarding the display of attributes.
Thanks again, and I wish you a great day.
