Can not add a section

Design help General
1

Hello there,

for some reason, I am unable to add a new section at the bottom of my page.
I can theoretically add it and it shows up on the Navigator but it does not show up on the Page itself. Any tips on how to fix this?
Thanks.

Here is my site Read-Only: LINK

Never mind, just had to reload the tab for some reason.
Now it works
