Embedded historical dates

It doesn’t seem like the endDate parameter is working. For example, if I use the following url (which is generated by the modal window from the WYSIWYG editor button provided from the plugin)

I should see data through March 4, 2016, right? But, with that exact url, the page renders data through April 15, 2016, rather than March 4. You can see it on the site here: http://www.napleshomeexpert.com/february-2016-34108/
