Anyone having trouble with the WK Lesson Filter?

I’m using the lesson filter to get vocab out of the way first, then radicals, then kanji. With that being said I went to filter a lesson today and the screen just goes blank. I’ve restarted chrome recently and while that fixed my vanished script issues, it appears I’m not out of the woods yet. Any advice? How do I troubleshoot this?

Update. It works if I have 1-0-5 for radicals, kanji, and vocab respectively. But if I do 0-0-5 like I have been, it goes white.

If you hit F12 and go to the console tab is there an error?

Also, in the future, please post any issues with this script in the dedicated topic for it. In this case, that’s [Userscript] WaniKani Lesson Filter.
