Classify Function predicting Nan Values instead of classes

I'm working on training an LSTM model.

Each input has 25 channels and sequenceLength of 313. There are 200 training samples.

Running the code outputs:

Final Predicted Value(predlabel), Training Data(lstm_arr), Training Label(classlabel):

All the predicted values are undefined values for some reason. Any reason why this is happening? What am I doing wrong?

btw I am running MATLAB on windows 10

Please refer to the following Why does LSTM sequence to label give undefined categories?
