Jupyter Notebook not seeing ingested custom data

This is a great repository and course - thanks!

I have successfully ingested data using the CSVDIR implementation - it is visible and works at both the CLI and in Jupyter.

I ingested another dataset successfully and it to is visible and works at the CLI, but it does not appear/cannot be access in Jupyter.

I tried a repo with its data and process, but these too also do not show up in Jupyter

UnknownBundle: No bundle registered with the name ‘yahoo_csv’

This has problably been covered already - my apologies - but I can seem to find a solution.
