KDE in Trixie: left mouse button actions differ from configurations

In Debian Trixie - KDE System Settings the configuration for the mouse 
click behavior is not working as expected. I am in detail referring to 
the following settings:

KDE Plasma Version: 6.3.4
KDE Frameworks Version: 6.13.0

KDE System Settings - Window Management - Windows Behavior - Window 
Actions - Inactive Inner Window Actions


I observe these configurations to work correctly for the RIGHT and 
MIDDLE click definitions, but for the LEFT mouse button definitions the 
actually applied actions differ from the configuration. I appears as if 
the list of actually applied left mouse button actions would be shifted 
to the list of definitions. I'll in the following first name the option 
in the Settings, and then behind a "-->" sign the actually observed 
functionality:

"Activate, raise and pass click" --> activates & passes click
"Activate and pass click" --> activates
"Activate" --> activates and raises
"Activate and raise" --> passes left click (no Activate and no Raise)
"Activate, pass click and raise on release" --> activates & raises & 
passes click
