Sidebar dissapeard on Homepage (builder)

Hi, my problem is that the sidebar has dissapeared on the front page (I am using Page builder). I am following the instruction on the right side under sidebar, saying I
To change the sidebar for static Front-Page or Posts-Page:
Go to the Widgets page
Click on “Sidebar Location”
Open the “Archive-Types” tab
Choose “Front-Page” or “Post-Index”
it doesn´t look exactly like suggested in the screenshot but similar. However, I have checked Archives Types etc but it´s still not showing.
Thank you in advance, Ariane
