Confusion matrix doesn't display properly

I am trying to plot a confusion matrix using the Logistic Regression for a multi-class dataset.

But the problem is when I plot the confusion matrix it only plot a confusion matrix for binary classification.

Here is where I am plotting it.

%matplotlib inline
import matplotlib.pyplot as plt 
import pandas as pd

dataframe = pd.read_csv("WA_Fn-UseC_-HR-Employee-Attrition.csv")

from sklearn.linear_model import LogisticRegression

LRModel = LogisticRegression(C=100, max_iter=5500)

LRModel.fit(X_train, y_train)

predicted_values_ = LRModel.predict(X_test)
from sklearn.metrics import confusion_matrix 

cm = confusion_matrix(y_test, predicted_values_)

misclassified = (y_test != predicted_values_).sum()
misclassified

import seaborn as sn

# plt.figure()
sn.heatmap(cm, annot=True)
plt.xlabel("Predicted")
plt.ylabel("Actual")

And I get this matrix as shown below.

Can someone tell me where I am doing wrong?
