As explained in the orangehelp files the test and score widget would provide an accuracy colum like "CA". I only have MSE RMSE MAE and R2 besides the times. Furthermore, the predictions widget has a tickmark in the lower left with text "show performance scores". Nothing happens if ticked or not. Last but not least the evaluation results won't be displayed in the confusion matrix, also. What am I doing wrong? I test and score with cross-validation or random sampling.
