Right content sidebar missing on mainpage

Dear all
Following the other thread on how to make the theme look like in the demo, I have almost completed my setup.
However I cannot manage to get the right content sidebar to show up on the main page, it only loads on all other types of posts or pages.

I have tried visibility settings and widget logic without succeeding so far.

I have a demo public for you to have a look at:

Kindly let me know what you think could help.
Many thanks in advance!
