Do you know where the "Source" filter comes from when browsing datasets through Open Data? We see one that we would like to clean up, but I can't find where the field is being pulled from. I don't see it anywhere in the item detail page in ArcGIS Online. The dataset owner said that rogue source is old from 2003 and the dataset has been updated several times since then.
Here is our Open Data site. Scroll down and look on the left side to filter by "Source".

Here is the dataset in Open Data that has the source we want to clean up:
https://data-seattlecitygis.opendata.arcgis.com/datasets/SeattleCityGIS::community-reporting-areas-3/about
I can't find anything on this page that corresponds with that source.
