How to make menu block item show up? I have a menu block composed of menu items with submenu items. 
Each menu item is displayed separately in a block.

They are all set to appear on every page, no restrictions. However if I were to access one of the submenu items, the entire menu item (including the submenu items) belonging to it does no longer appear.

I have checked in variables from template_preprocess_page, the region where the menu item block should appear is showing as empty.

How can I make it show up?
I have found the issue, "Make the starting level follow the active menu item." needs to be unticked.
