Text input broken somehow

Recently, I was doign an assignment using Kami, and the text boxes aren’t working properly. I want to type in the word “Adenine”, but When I press the d, it automatically deletes it and replaces it with the word “gives”. I am having the same issue with the letter e, Kami responding with “is” At one point I got the word “he” but I can’t replicate that one. I got around this by typing after Kami replaced it and deleting the replacement word. I had a look around and my setting seem completely fine. Is this a bug?

Are you using the new version? Because i never exprienced this problem on the new version
