CppCheck Plugin annotations not working in Editor until first "Apply" in preferences

I could start the CppCheck from the Analyze menu and it showed hints.

But while clang-tidy was flooding my Soruce Editor with hints, CppCheck hints were not shown.

I had a look at the Edit => Preferences => Analyzer => CppCheck and the settings were the same as in the explicit call from Menu Analyze => CppCheck.
However, no hints annotations in the Source Editor.
The manual tells me:
"To specify the settings above for the automatically run checks, select Edit > Preferences > Analyzer > CppCheck."

By "accident" it started to work with annotations when I pressed "Apply" before closing the Preferences for the first time. Without this "apply" there was not annotation.

As all checkmarks in the Preferences Dialog were set reasonable, I had always closed the Preferences with the [x] in the upper corner ...

How about an additional checkmark to a activate/de-activate "automatically run checks" in the CppCheck Preferences Panel?

Or have it automatically running when the plugin is active?
