Hello, hello. Thanks for your work! I took a look with @Snooz82 at the reason why the github actions for this PR is failing.

It turns out that the learning_objectives.md document is used to generate numbers. So it's better to not link any terms when you're working with the LO's themselves.

Example to avoid

Can you remove those? The actions should then work.
