File window in categories shows all files although hierarchical mode is of

[frankdarwin]

If I select in the categories a directory in the directory tree which has subdirectories, all files are shown in the file window, although the hierarchical mode is of (see "Show Files.jpg").
Example:
The selection in the directory tree is "Alsfeld".
The folder "Alsfeld" contains no files, but has 2 subfolders (see "Categories Tree.jpg").
But in the file window all 36 files of the subfolders are shown (see "File Window.jpg").
If I select a folder with subfolders in Media & Folders, it is different.
What is the reason for this?

A category implicitly contains all files in their child-categories, recursively.

If you have  something like

A
|-a
|-b
|-c

and a,b,c contain 10 different files each, clicking on A will show 30 files (the files contained in the child categories a,b,c).
