Notebooks failed to load after running them externally on Jupyter Lab

When I create a notebook in DataSpell and later on work on it externally on Jupyter Lab, I'm not able to load it on DataSpell.

When I try to open it (double click) nothing will happen, trying to open it via `run all` (contextual menu) will show the following error in the Jupyter log:

[W 2022-07-23 21:00:22.323 LabApp] Config option `kernel_spec_manager_class` not recognized by `LabApp`.

I can follow a link to open the notebook on a browser but it won't open on DataSpell (that is what I want).

Just checking if anybody else had the same problem. I guess Jupyter Lab is inserting something in the notebook that makes DataSpell fails.
