EDIT: Solved by looking for it in this dictionary: https://www.kanjisho.com/kanji/軀 which has it properly listed and contains parts which work on the menu. I’m leaving this open for a bit, I’ll try to contact the author of jotoba and see if they can figure what database kanjisho is using, and use that one
This seems to affect these kanji, at least, and I suspect there are many more:
軀
剝
I like to select the parts off the “radical” menu on these sites, however, it doesn’t work on these kanji, because the database entry is empty.
EDIT: If such a database even exists….
