When I am in the Site Editor and add the Chart, Dataset, or Summary Statistic cards, I am asked to select a dataset. The dialog shows that I have no datasets available and searching on tags/keywords returns no results. However, we have several datasets that are searchable from the site and show up under the Data tab in the site configuration. While we have some datasets that are being served from a 10.0 server, we have two datasets that are being served from our local 10.5 server, and I thought at least those would be available. Is there another step to making these datasets available for the Chart, Dataset and Summary Statistics cards?
