Why is the quality still "n/a"?

 

After I used the script "CSV2FXT" on Eareview, the 2 issues below found and who knows how to fix?


1. I downloaded EurUsd.csv from dukascopy.com.
    I opened M1 chart and convert the EurUsd.csv successfully, then H1 chart also successfully. 
    However after testing, the quality is always "n/a". How can I get the quality improved to over 90%?


2. After opening the testing chart, I found the weekend data are also in the chart. 

    How to remove or hide the data that haven't any change? 

 

I followed the script instruction to connect MT4 to my broker before data converting.
