Pk3DS Static Encounter Editor Errors

[King Feraligatr]

Hello there. I'm working on a personal hack of Ultra Moon and when I've been trying to edit the species of a static encounter (everything else is fine though), I get this nasty looking error: https://pastebin.com/9Pd02Gay . Not aborting the operation causes that static encounter to disappear off the list as well (I'm not dumb enough to save after doing that though). I don't know if it's an error on my end, but I'd like some help or insight into what's causing it, barring an out of bounds array index.
