Incorrect Parameters in Expert Advisor

 
MetaQuotes: I've been doing some testing with the strategy tester component in mt. The specific script that I'm running includes the Bollinger Band indicator. After performing a back-test in the strategy tester, I can open the chart as normal that will display the locations of where orders are being placed. On the top, there's a comment displaying the parameters for the previously tested expert advisor. However, it's showing incorrect parameters for the previously test.

I think it's to do with the way the program handles user defined values for expert properties and it's default values, because even though I compiled the ea just before the test with new default parameters, the expert properties dialog doesn't update to the new values.
