I was stuck there for a bit, cant even see the option so I was running around like crazy trying to find where it even was. But if you click above the top visible option it'll register and you can orogress.
Maybe because i’m on a Steam Deck, but that didn’t work for me. In the end, I found out that if you go to the school on a Saturday morning, there’s one less option on the list and so the option becomes clickable. Definitely yikes though
