add side bar on page template in Events calendar

Hi,

On this page where the events calendar is displayed: https://www.fronikboerderij.nl/agenda/ I want a sidebar on the left, without navigation. I don’t want any content or widget to appear there. BUt now it shows the entire navigation of the website.

In the settings of Events Calendar I chose under the option “Display” and then “Events Template” for “standard page template”.
In the Enfold settings I chose under “Sidebars” for a left sidebar on a page and I deselected the button “page sidebar navigation”. But this does not work.

Somehow Events Calendar seems to choose the template of the archive page instead of the page template. Because when I tweak these settings in Enfold, it has effect. But I don’t know how to get rid of the navigation list on the left side of the page.

Hope you can help me out with this issue, thanks a lot!
