Global Variable Bug

Hi all

I’ve been using global variable in many ways, and I just found something weird is happening.
Once I set a global variable and manage my prototype to change its value on internet browser, it changes default value of the global variable on Axure.
This has never been happened in the past version of Axure and I think it is a bug.
I can see this issue even after I set a function for resetting the global variable in the end of the process.
Hope this issue would be fixed ASAP.

Thank you.
