JQL question with "WAS"

Question

I have the following JQL I want to use to get all issues that are billable, that were closed within the current month. Instead it's showing all from the previous month as well.. What is wrong with my JQL?

Billable= Yes AND status = Closed AND status WAS Closed DURING (startOfMonth(), endOfMonth()) ORDER BY project, created asc

Try this:

Billable= Yes AND status = Closed AND status CHANGED to Closed DURING (startOfMonth(), endOfMonth()) ORDER BY project, created asc
