Total are not summing up correctly in Pivot table in dashboards

[SUDHEERBABUM]

I have created the formula KPI using three KPI's like ( KPI1 - (KPI2+KPI3)) and when i placed this KPI in Pivot Table visualization  it's not calculating correctly.. if i place these three KPI's separately in visualization it's working correctly but this formula KPI is not working correctly

Can you share more about your KPIs and the results (screenshots, what is it calculating, what are you showing in your pivot table, what is the expected result vs the actual result, is it showing correctly in other types of visualizations, etc).
