Hello!
I have a hosted feature in ArcGIS online. This layer is included in a webmap, which serves as the source for a dashboard.
Somehow, this source layer has had a filter applied to it, which filters out a large segment of my data. I can remove this filter within the webmap, which lets me see all of the data as expected. However, doing so indicates that this filter setting is stored only in the webmap. If I "reset to source layer properties", the filter comes back.

When I use this data anywhere other than this webmap, the filter still seems to be applied. This is true on the data tab of this layer's item page, as well as when I add the portal item to an ArcGIS Pro document. Outside the web map, there isn't any indication that the rest of the data exists at all.
How can I remove this filter from the source layer's properties?
