Date Hierarchy is changing from month year to year only

[RobBenco]

I have a visual that I show the date hierarch Year and month.  But when I close and open the report or publish the report to our PowerBI server, only date heirarchy by year is displayed.  How do I prevent the visual from changing and keep the year month hierarchy.

This is how I want it to look.

This is how it looks when it is reopened or opened from our PowerBI server

Publish it when the hierarchy is expanded.
