How to search a word in vocab that contains the letter "K" without moving vocab to knonw

so I use the vocab section a lot because I feel like I will learn the vocab better if I link different context of the word I am tryin to learn. Now here’s the problem. Whenever a word I am looking for contains K it moves all the vocab appearing on the list to known because of hot key. Is there a fix?

We are familiar with that bug and we are looking into it. We will have it fixed soon.
Thanks for your patience!
