How to properly render a Calendar view title in a month display? I have a calendar view set up as shown in these screen shots. Everything is working nicely, except the title. I'd like the title to be only the month, not the first of the month.

That is, instead of the below screen shot reading December 1, 2014, I'd like it to render only December 2014 (omitting the "1st").

Is there an answer that I'm missing in the Add Header area?

Update: Contextual Filter
There is a bug in the date module that causes this issue. I'm not sure if the latest version of the module resolves it or not. If it doesn't, then the workaround in #20 in the thread at https://www.drupal.org/node/2294973 will fix the issue.
