Firstly, thank you so much 
Ivo (and 
Gaurav and other testers, contributers) for 
ClassicShell. 
I would wish that all Windows able to Classical (Copy-move dialogs, NoAutoArrange/Sorting, NoDirectWrite, and a lot more). Unfortunately, it was not destined to be.
I want to report a issue.
Re-produce:
1) Open the settings of Classic Start Menu.
2) Click to 
Customize Start Menu.
3) Drag-to-drop "
Log off" to under of the 
Shutdown dialoag the from 
Aviable commands. 
Example screenshot.4) Result: Although the "
Log off" feature added to inside (as jumplist?) of the 
Shutdown..., it can't display in there.
