"Run Cell" codelens is not showing above marked cells in .py files

Environment data

• VS Code version: 1.51.1
• Extension version (available under the Extensions sidebar):
  -- Python: v2020.11.358366026
  -- Jupyter: v2020.11.358541065
• OS and version: macOS Catalina 10.15.6
• Python version (& distribution if applicable, e.g. Anaconda): 3.8.6
• IPython version: 7.10.0
• Jupyter version: 1.0.0
• Value of the python.languageServer setting: Jedi

Expected behaviour

The CodeLens
Run Cell | Run Above | Debug Cell
above each cell marked by
#%%
should be showing but is not. It was working perfectly until a few days ago. When I opened by laptop this morning, the codelens were not showing anymore above code cells. The "Jupyter: Enable Cell Code Lens" setting is enabled in my VSCode settings. I believe that, for some reason, VSCode does not detect that there are any code cells in the .py file.

Steps to reproduce:

1. Create a python file test.py
2. Create a code cell

#%% This is a cell
msg = 'Hello world'
print(msg)

I figured it out. It was due to the jupyter.codeLenses setting.

For anyone who has similar issues, open your settings.json file, and replace
"jupyter.codeLenses": "python.datascience.runcell, python.datascience.runallcellsabove",
with
"jupyter.codeLenses": "jupyter.runcell, jupyter.runallcellsabove",

Apparently, the first one used to work and was replaced with the second one, but the settings were not automatically modified to take this change into account.
