this is default behavior from module Magento_Theme. Every theme in storefront will have inheritance layout page even your theme have no parent
Nothing wrong with dropdown in categories design section show layout like that. That is option allow your owner site can custom your category page layout from backend

@mrtuvn, this is wrong:

Every theme in storefront will have inheritance layout page even your theme have no parent

I'm totally allowed to override this and provide my own custom page layouts. Forcing page layouts in the back-office that are not part of the available themes mean that the webmaster may chose a page layout that doesn't exist and have an expected result in the end.

this is choice preferences you can choose set from backend or customise in theme. Theme will always get high priority. No problem to customise categories pagelayout in your custom theme and it's can be done via xml But sometimes you will need update in backend instead hardcode fix layout in theme. Change page layout in config is better and managements than hard code in some xml layout in theme. I think we should not depend on any theme here. Seriously why we need to force load layout follow current set theme here
