Sidebar regions are not showing in droopler_subtheme block regions demonstration. However they are showing in the themes block layout.

I was wondering if there are any suggestions or tips on how to fix this issue of sidebars. Is it a bug?

I believe this is a duplicate of an issue I filed last spring : https://www.drupal.org/project/droopler/issues/3359701 →

You closed my post as duplicate. However, you did not yourself find or mentioned any solution to the problem in your own post. Could you please guide me to what exactly needs to be done to achieve the desired.

Well, this issue is indeed a duplicate of mine. But I do not have an exact solution to show the sidebars since I chose not to use Droopler for the project I needed them for. Sorry, as you can see in my issue, I asked for more information but never got a reply.
