I get this problem when having installed jupyterlab/toc version 2 or 3 while having juptyerlab version <2. Try something like jupyter labextension install @jupyterlab/toc@1.0.1
TOC 4.0.0 which requires JupyterLab 2.x has a fix for #128 which disable this capability and if desired can be enabled on JupyterLab advanced settings editor.
I don't understand why are 4.2, 4.2.1 foldable? It was supposed to be not because it has no content....?
I'm faced with this problem when I reinstall toc extension.
