Using a button is not the best idea I think. Why not use set analysis in your expressions. So for example sum({<yearmonth=>}Amount) with this formula you will get a sum of all amounts even when you have filtered on yearmonth.
if you want to do it by button, there is an action to clear the field.
Maybe use button with action like, "Clear selections in field" otherwise set analysis is better approach.
alternatively, you can maybe think that field to use an alternative state.
