Clicking on data binding doesn't display Expression

If I click on a Data Binding (in the Design View area) it is not selected in the Properties Panel, but if selected in Code View it is…?

This is a site developed in DW with DMX Extensions and being worked upon within Wappler…

Probably missing something so please don’t discount user error here

Am I being a Muppet once again?
