Thanks for writing in! Did you made some template customization to display the event page? Could you please insert the code of your template so that we can check it out and add some elements in it. This is to correct the container and make sure that the sidebar will be displayed on the event page properly.
Okay, figured this out. It was a setting in the plugin. In case anyone else needs this info I am using Events Maker and I had to uncheck “Enable to use default templates” in EM settings under the Templates tab.
