Can't see tables in Object Exporer for Cross-Connection Query

I created a cross-connection query, and as expected, the object explorer shows the 2 connections. But i am unable to click the black triangles to drill down into the tables. When clicking, nothing happens. TDP v4.0.0.624

I have never seen that before. Can you open one connection only? Then open up cross-connection Query Builder and look at the object explorer that is in the Navigation manager? You pic shows separate object explorer.

Also what is the viewtype. It needs to be Connection list

Unfortunately, same issue.

Does this only happen with those specific connections? If you chose a different pair of connections, would the drop down arrows work?

Can you open a support case? I would like them to help you turn on logging and send back a support bundle.
