Data Sources Disappearing

When creating a BigQuery Custom Query data source we are able to create the data source, add calc fields and explore the data. Once we go back to the table listing our data sources the new source shows up but then disappears shortly there after and never returns.

We first noticed this happening yesterday (6/11) and the issue continues to persist today (6/12). How can we resolve this as it is preventing us from creating necessary reports. I do see previous reports of this same issue.

How can we resolve.

We are encountering the same problem. We had a couple of Data Sources created early yesterday (6/11) finally appear in the listing. However the same problem appears to persist today - a newly created Data Source appears in the listing briefly, then disappears. The recently created Data Sources are also available when creating we try to add them to a report.
