Geiriadur Harri Potter. Can't ignore a word

On level 160 there is a Welsh word with no English definition. I’m trying to ignore it but it won’t let me. It keeps on trying to teach me a word I can’t learn. Not a problem on the Android app as definitionless words aren’t taught. Ignoring words on the app still works, ignoring words without definition, or with them, has worked on other courses. As I’m having problems with learning new words via the app this is a bugbear.

If you know the English definition, I’ll be happy to add it for you. Please send me a private message.

This is a one time fix, any further issues regarding blank fields should be discussed with the course creator.
