I am working on a 3 classes classification problem and my confusion matrix is getting messed up. It does not show class 1.

 ![multi-run_confusion_matrix](https://us1.discourse-cdn.com/flex020/uploads/wandb/original/2X/d/db00d90402775cbd38aa10db03d568c86fe1b6b1.png)

The test accuracy for all three classes is 95% and all three classes are actually in the dataset.

```auto
        # log data for the confusion matrix
        wandb.log({"conf_mat" : wandb.plot.confusion_matrix(probs=None,
                        y_true=y_test_true, preds=y_test_pred,
                        class_names=labels)})

```

Any idea how to solve this issue?
