I believe it may be an issue with my theme (it is called Divi by Elegant Themes). Everything was displaying properly before. I did update to the latest version of theme a few days ago, and not sure if the calendar went away when I did that (I just noticed it today).
Any help you can provide would be greatly appreciated.
We check those forums a bit more than once per week, so hopefully we will be able to get to your question there.
