Code not being generated for some layout editor screens

I was using the layout editor to build around 35 screens for my project. After deploying, I noticed that 15 of my screens were blank in the preview. Even though I had built these screens in the layout editor, there was no code generated for these screens since the day I started the project. This is also what is happening for the other blank screens on the preview.

I’ve attached a photo of one of the screens I built in the layout editor that has no corresponding code. I am not sure as to why the code is not being generated for these screens.
