Module development and code questions

I have a default Layout created for an entity - a content type in this case. This means every time a node of that type is created, it's created with the default layout applied. That's expected.

However, what I've noticed is that when node is created (saved for the first time, either through UI or programmatically) layout_builder__layout field is empty. In order to populate it, need to open the layout and save.
