Hello, I have created [a Renku pet project](https://dev.renku.ch/projects/lorenzo.cavazzi.tech/zurich-air-quality) to test `renku dataset`.

I initially created a dataset, added a file and run a script to clean data that takes 2 parameters:

- an `--input-path` to read the dirty data
- an `--output-path` to write a cleaned csv file.

The (here simplified) command was:  
`renku run python clean_data.py --input-path air-quality/file.csv --output-path processed/file.csv`  
Then I re-run a similar command including also an `--input` directory to force renku updating when adding any file to the folder:  
`renku run python clean_data.py --input-path air-quality/file.csv --output-path processed/file.csv --input air-quality/`  
At this point, I tried to add another file to the dataset, that is downloaded and added to the input folder `air-quality/`. I expected the update to run automatically, but this didn’t happen. Is this correct?  
Then I typed `renku update` but I got an error.  
I believe I created extra dirty workflows that should be removed. Does this make sense? How can I get rid of the redundant workflow form `.renku/workflows` in a clean way?
