Wrong data applying

Hi guys, I've been applying some algorithms like Naive Bayes, k-NN, and Decision Tree, the process works well, but the preprocessing operation with the Remove Duplicate method keeps on returning this result, no matter which attributes I changed.
  
Any support would be perfect! Thanks so much!

    Hi @NgocNguyen2001

    If you select subset or single in "attribute filter type" you need to provide the attributes that you want to consider 

    Is that your case?

    Yes, I have set it to the no missing values but it still doesn't work at all

    Hi @NgocNguyen2001

    please check that you haven't missing values in any example in your attributes. 
    If you have missing values in any example of your attributes this option will ignore all of them.

    Best,
