Can't buy bonus lesson

I want to buy the Idiom lesson for Italian, but it says I do not have enough slots or something. Can someone help?

You have to get past Food and Animals. Then the bonus skill slots open.

Going to move into troubleshooting (questions or bugs). Like easuu mentioned you can only unlock the bonus skills once you've progressed enough in the tree.
