The Formula in this cell differs from the formula in this area of the spreadsheet

I'm new to Jet Reports, I desgined a Balance sheet  & Profit and loss. When I run the repors I get a green triangle in some cells with a warning of "The Formula in this cell differs from the formula in this area of the spreadsheet " I double check my formulas in desgin mode and all looks good. I click on ignore error , the warning goes away but when i refresh the report the error comes back again. How can i trouble shoot and get rid of the warning message?
