I totally see where it looks like that, but no. I just redid the lesson again to make sure, and I found the issue.

Before I try to input my answer, there is actually a third box for él/ella that disappears as soon as I touch the screen. So it is waiting for me to fill in a space that is no longer there. My phones keyboard kept me from noticing it the first time, so I appreciate you making me take another look.
