not sure what happened to sidebar on some pages

I was trying to remove the Blix calendar from my sidebar, and now all of a sudden half my sidebar is missing from some of my category pages. I’m not sure what code I need to add back in to what page (next time I’ll back up before experimenting). My site is at https://stc-suncoast.org/. I would like every page of the site to have the same sidebar as the home page. But for jobs and news (e.g., https://stc-suncoast.org/archives/category/jobs/), the sidebar is mostly gone.
