As you can see in this screenshot http://prntscr.com/iaak4l. I selected "last 12 months" in select dates section of twitter ads which is also including this month. However, data that pulled with this condition brings last 13 months that starts with 2017-02 and ends with 2018-02 (both included).
It breaks our weekly and monthly reports because of this date issue. Is it a bug? How can i solve this problem?
