Settings not changing accordingly

 

hi, this is rather odd but ive noticed my MT5 settings when running an EA simply does not change when i make certain adjustments. For example, if i change the Bollinger Band Std from 1 to 4, the only chart visual bands do not change as ive seen them do. This is impact the results from when i print certain values. 

I've noticed that when i change the date i want the EA to backtest, the EA will not review the exact same dates as ive selected. I've seen it change but not neccesarily change to the correct dates. Ive seen other minor issues but im starting to think is a major problem which needs resolving. Any thoughts?
