Unfortunately, not much we can suggest to resolve this.
The settings need to be changed for the Events Archive Page as that is what WordPress considers is the Events Calendars View. Not sure where that is in your theme, but the theme developer maybe to help out on that.
The other option is to edit the templates by following our themer’s guide:
https://theeventscalendar.com/support/documentation/events-calendar-themers-guide/
Then you could add the sidebar by manually coding it in and change the css to format correctly.
Either way I am afraid it is beyond the support we can provide to provide the entire solution for this. I can try to answer more questions about the Events Calendar if you have them related to this.
Thanks
