The "Potential monthly spend" column in Open and Ignored recommendations is confusing. The data shows the Current Spend. To my mind a potential spend is what you would spend after a change (logically in this recommendations page - after you implement the recommended change). Please consider changing the data shown, changing the column heading or adding a column to show the new spend you'll achieve if you make the recommended change. I would name it "Potential Monthly spend" but that heading is taken.
