How to properly package game for release to public

Hey,

So I have a bit of a problem with packaging of my game for public releases.
If I package my game by clicking Platforms → Windows → Package Project (with “Shipping” ticked on) and I turn on my packaged game, I still have debug messages on screen.
When I package my game with a help of “Project Launcher” with these settings:


Then I don’t have a Debug Messages on Screen in packaged game, but it seems that It “package” my project file structure and uproject file:

And this folder content is from a packaged game folder if u wonder:

So, for now this doesn’t bother me since these are more test builds, but I’m running out of ideas on how to package the game so that the project’s folder structures can’t be previewed once it’s playable (I’m also worried about the uproject file that’s in there).
