How to handle duplicate variables in definition of Report

I have 3 process models A, B, C having same process variable "isJeopReturnBack" of type boolean. Now I have a process report for these process models in that report the definition has 3 duplicate variables viz "isJeopReturnBack", "isJeopReturnBack" and "isJeopReturnBack". Attached is the screenshot of the same. Why is this appearing thrice ?

Thank you.
