I also don’t remember to show corp-hangar below Station-services (only items and ships).
But there where another recent change, that removed some symbols from the Neocom-menue such as “corp deliveries”, “corp hangars”, “shiphangar” and “item hangar”.
Each of them can be opend (and remembered* as open) via drag and drop, shift+click or setting the key-shortcuts.

*remembered separatly for Upwell-Structures and NPC-Stations
edit: oh and strg+x -> strg+v will do the move from one hangar location to another for you
