jupyterlab_default: false has no effect

[DavidNemeskey]

I installed the repo on a server, and logged in with a user. I was expecting to see a regular Jupyter notebook interface; however, I was greeted by JupyterLab instead. I tried removing the /lab part from the URL, but I get redirected to there nevertheless.

The variable jupyterlab_default had been set to false in the host_vars file. I followed the installation instructions here.
