I have a csv file where the last column is titled with "label". I set it as "binomial" when using "import configuration wizard". This column only has two types: "N" and "R". However, running the loading csv process gives the following error message:

Process failed
Cannot map another string for binary attribute: already mapped two strings (N,R). The third string that was tried to add : <tt>?</tt>

Do you have questionmarks in addition to N and R in your data? In that case, try to set the attribute as polynominal, and use the operator Declare Missing Value to define the questionmarks as missing.

Best regards,
