Possible bug with the Glossary link on the top of a lesson

[skeating]

hi

I am developing a lesson and have filled in items in the learners/reference.md file. But when I click on the Glossary link at the top of the page it redirects me to the first lesson of this repo.

Interestingly if I go back from that it then adds my lesson as the second lesson with this one as the first. I suspect somewhere the HTML that was built the first time I ran a build has not been cleaned up after I have made changes to my repo.

My repo is https://github.com/SAFEHR-data/omop-carpentries
and I am currently using the "festival" branch as I'm working on a ninety minute taster session for the overall course
