If the Undyne the Undying preset does not appear, you can click on "Reset" button to reset the presets to default and it should appear.

Hopefully this helps. Cheers!

i did the same too. but i skipped to new home so i set everything to "Killed". and when i interacted with the locks it did the normal, neutral run text. instead of "he leaves them in the kitchen and the hallway.". i didnt dare continue past the lockers and i set preset to sans battle.
