Strategy Tester Not Working?

 
I have an EA with parameter inputs and it's working fine. However, when I changed some of the parameter inputs of the EA and run Strategy Tester again, Strategy Tester keeps giving the same results. The report shows the same numbers, nothing changed. Why? Changing the inputs should have affected the results, but all the numbers still the same. What's wrong? Please help. Thank you.
 
I right click on the EA that attaches to the chart (smiling face) and click on "Expert Advisors" -> "Properties" and change the inputs from there. However, Strategy Tester keeps giving me the same results. Please help. Thank you.
