Power BI Dataflow Using OData Not Being Able To Select An Existing Data Connection

My details are not different. It's the same Azure DevOps URL, and it's the same user from when I created the Data Connection as the one creating the Data. I have been creating Dataflows for over a year now and I have never seen a value in those drop downs to allow me to select an existing Data Connection. There seems to be something fundamentally wrong. I will look at creating a Pro Ticket.

There is no solution to this as you can perform the steps listed in this post when you are in the edit view on the server you can make these changes, but when you try to save it fails. I feel it fails due to SQL injection or other injection reasons.
