The reason is that, in this case, only the files in the directory itself are added. We do not, by default, add the whole directory tree recursively, because it could easily take ages on a massive directory tree. The only case when it will descend into sub-directories automatically is when the "starting" directory did not contain any files at all. And even then, it only descends to the next level, until some file have been found.

If you which to add a whole directory tree, in a fully recursive manner, you can do so via "File" -> "Open Folder Recursively".

Yep - that'd be it then. Didn't realise! Will take note for next time. Thank you!
