Why i get Test error 0% in the Modulation Classification with Deep Learning example on GOLD_XYZ_O​SC.0001_10​24.hdf5 dataset?

Matlab Example Link:

https://www.mathworks.com/help/deeplearning/ug/modulation-classification-with-deep-learning.html

On Command window

openExample('deeplearning_shared/ModulationClassificationWithDeepLearningExample')

I want to test the above MATALB example on the dataset which link is given above. 5 modulation types of dataset which are same with the the builtin example of MATALB. that is ["BPSK","8PSK","64QAM","QPSK","16QAM"]

I have taken only three modultaion types that is "BPSK","QPSK",8PSK" to test that MATLAB example.

Firslty i have preprocess the dataset and make it same with matlab example then i have given that path of my dataset to MATLAB example but it gives me test error 0%. Why that MATLAB example is not picking up my dataset.

I have upload the preprocessing dataset matlab file.
