Tear off menus disapear

I tore off a submenu and it disapeared. Is there a way to get it back.
This has happened before and after a while and me clicking everthing it comes back. I don't know why or what I did.

There is a blank arrow in the main menu for the tear off.

There is a blank arrow in the main menu for the tear off.

Please can you post here the screenshot of that "blank arrow"?

When I say blank arrow I mean the menu above the one I tore off does not have an arrow.
Normally when you tear off a menu the the arrow disapears.

So as I understand, you make "Tear Off" for one menu and now when you click the menu icon you get nothing. Is this right?

Try clicking where the name of the submenu is.

Example: Click Control Panel (Menus Name) in the main menu.
