The fill-in-the-blank word is showing up on the wrong side of the sentence.
The ones where it makes you type in the blank at the end of the sentence. One of them was translated literally as, “or her you” (או היא אתה) instead of “you or her” (אתה או היא) where I was supposed to type in the final word (היא). I was using the browser version on my laptop for this, but idk if that means anything.
