Is the low accuracy problem related to my data preprocessing

Dear author,
hello, your work is very helpful to us, I had a problem when reproducing the model, my data preprocessing used the getdata file of this project to obtain data, but I did not do filtering processing, and the problem of model accuracy skewness occurred. Is this related to my data preprocessing.
