Can't see the bottom line of code

Hello there.
I stumbled across a little problem in the command line course (https://www.codecademy.com/courses/learn-the-command-line/lessons/redirection/exercises/sort)
Every time I reach the bottom of the terminal after giving it some commands, I’m unable to fully see the last line of code. I can’t scroll down further.
So I thought this might be the fault of my browser, so I switched it.
First it worked well again but a day later the same problem occurred in the other browser as well.
Does anyone know how to fix this or might this be a problem from the code academy website itself?
Thanks in advance!

I’ve not come across that problem I’m afraid but clear as a command should remove the earlier lines of text which might make it readable again. There are a few other tricks such as “Ctrl + L” which do the same sort of thing if for some reason that doesn’t work.
