Interesting, my gut says it might have something to do with the fact that there is only one question for radicals, where kanji and vocab have two. Lately been focusing on a major overhaul of self-study-plus. so won't be looking at this one for a while sorry.
Issue when reviewing radicals
I noticed that the status of radicals doesn't appear after entering the correct answer. For example, usually after entering the correct name for the radical, the green or red bubble pops up saying when it's Guru, apprentice, etc. The script seems to be preventing this for radicals but not kanji or vocabulary.
