It's expected because we don't have binary-classification for now, which means all classification is multi-classification. Do we want to update test metric for that?

Thanks for @LittleLittleCloud explanation, I may have misunderstood as see the information from https://docs.microsoft.com/en-us/dotnet/machine-learning/tutorials/sentiment-analysis-model-builder, then think this test matrix is for binary classification.

Do I need to close this issue since this is expected?
