minibatchpredict or predict with stateful classify at simulink

I trained LSTM for fault detecting.

when I use "minibatchpredict" or "predict" command at matlab command window, it is work very well.

scores = minibatchpredict(net,XTest);

or

YPred = predict(net, XTest);

But when I use Stateful Classify at simulink, it is very bad.

I use all time same data and net.

Matlab command window work very well with minibatchpredict and predict command but simulink is not good Stateful Classify.

Why?
