Blocks on Widgets not working

Hi,

The blocks only work on widget if there is an existing block as well on the content.

I have advance column blocks on my footer widgets. They work on homepage because I have advance column in the body content as well.

But in another page, the footer column widget is not showing up as column because I don’t have an advance column in the content.

Can I use the blocks on widgets or not?

Thank you
