Inserting rows or columns formulas dont add up

I have a spread sheet with formulas totalling number across columns and also adding up columns. When I insert a new row the formulas dont update. I have tried tables and I have set the reference to extend formulas and functions. Sometimes the new insert is added at the bottom but not across. Am attaching a sample sheet. If I insert a row at 12 and key a number it calculates sometimes and not others. Help
