sidebar stays visible

Hello, I asked catch salesteam which theme is the best for the bakery website for my daughter. The answer was: catch store. Before taking the decision to buy this theme, I have installed the free version, to show the possibilities. The URL is: https://laura.hagmeijer.nl The first problem is the frontpage. There must not be a sidebar. But removing the sidebar seems impossible. I changed the layout settings in full width no sidebar and removed all widgets from the sidebar. Also I changed in the fast methode to change the website I cannot input: no sidebar full with. After confirmation the standard lay out returns. On the home page I cannot change the lay out in no sidebar full with. Is there a solution for this. If not maybe I better can switch to another theme. Kind regards Hans Hagmeijer
