Homepage side bar

Hi, I set up primary side bar on the right of my website (https://climateinformed.w.uib.no/) and it appears on the homepage and all the other pages. I don't know what I have done while I was trying to use feature content but the side bar disappears on the homepage. It is however visible on all other pages. What should I do to change it back so that the side bar appears on the homepage again? Kind regards, Mandy
