Just checked my save game on this.
The first one (from common) under spirited away is called "Afterwards..." - as for how to trigger it I'm not exactly sure as it's been a while, may have something to do with the test of courage and the people you pick there.
The ending you're missing is the PSX Epilogue - It can only be accessed through the shortcut menu, apparently included as a bonus from the translators. Source: https://tlwiki.org/index.php?title=Talk:Never_7
Hope it helps!
