Does automodel calculate performance for mulitiple classes in predictive analysis ?

I am working on a class project and curious if to check prediction for a polynomial class.
The original label consists of 15 different classes, on applying filter and selecting only 2 classes and running it through the automodel I was able to get the ROC comparison aswell as other performance values such as AUC , sensitivity , specificity etc. 
When I applied the filter to select 3 classes and ran it through automodel, I was unable to get those those performance values and ROC comparison.

Can I please get an explanation and solution for this ?

    AUC is simply not defined for 3 classes. Also Sensitivty and Specifity is only defined for 2 classes.
