AnkiDroid Error Saving Note


I wanted to add my leeches from Wanikani to Anki. Unfortunately I get error messages when I want to save a new card to a deck.
I don’t know much about Ankidroid but I hope some of you can help me out.

Thanks in advance.

Using Wanikani template for ankidroid

Maybe one of our Anki gurus can help? @hinekidori @polv
