Uncheck Timeframe for Currency Pair in History Center

 

Hey all. So i am trying to figure out how to uncheck the 1 minute timeframe from the History Center for the EUR/USD currency pair.
I'm only looking to get historical data for the 5 minute timeframe, but i can't seem to find a way to unselect it (so that it's greyed out and doesn't download any records from my broker)

I've already tried deleting the entire History folder in my MT4 data folder, but the 1 minute time frame is still selected for some reason

Does anybody know how i can unselect this so i only have the timeframes i want?

Reason:
