The dataset generation failed because of a cast error

Error code:   DatasetGenerationCastError
Exception:    DatasetGenerationCastError
Message:      An error occurred while generating the dataset

All the data files must have the same columns, but at some point there are 1 new columns ({'Feature Completion Time (days)'}) and 1 missing columns ({'Feature Completion Time'}).

This happened while the csv dataset builder was generating data using

hf://datasets/naushadnizarali/developer-stats/developer-stats.csv (at revision 0bc7aefe8dfb18ea2aeb9b01795f8f4bd390a17a)

Please either edit the data files to have matching columns, or separate them into different configurations (see docs at https://hf.co/docs/hub/datasets-manual-configuration#multiple-configurations)
