Binomial classification positive class remapping again [Reported]

ammargh

Hi
Please check the process bellow.
Looking at the accuracy you can see that the "true no" column sums up to 5  but if you check the sensitivity, specificity, or f-measure it sums up to 9.

It looks that the data is not remapped in the confusion matrix when the accuracy is shown.

Another thing is, I have used the original port from   "remap binomials" component which should provide me the original not remapped data output was remapped for measures other than accuracy
