Edit the front page layout, make new custom block, give it Admin label + description.

Save layout. Come back later because you changed your mind and try editing that admin description. It ignores you.

Accepted answer

I was able to reproduce. The key step you did not mention was that you have to check "Make this block reusable".

This is a bug. I'll report.

One workaround: instead of creating the reusable block within the Layout at admin/structure/layouts, create that Custom block in the Custom block UI at admin/structure/block, and THEN place that block in your layouts.

Additionally, if you do the above, you'll be able to change admin  label and description in the Layout UI. This time, it will respect your changes.

I can't reproduce this. It's working for me. Wondering if you pressed "Save" in the layout after pressing "Update block"? This happens to me all the time!

Yes, edit text, Update Block, Save Layout...

still as the image shows. 

I checked the perms for the active config layout files; 664.
So probably a Nginx issue ?

I manually edited layout.layout.home.json, removed the admin description.

Refresh the layout page, and the description auto-applied.
