Can't See Structure Properties After Upgrade

Unknown

Hi,
I recently upgraded from 5.4 to 5.8 and now whenever I try to use the "Build Data" input mapping on a Flow Data Extension structure
I see the attached image instead of the list of inputs that Ive come to expect.
How do I find the Build Data input properties for this structure?

When the “max” number of properties is exceeded on a given type it prompts you to select which properties to include.
To do this you must click the “[b]…[/b]” button in the [b]Properties[/b] section (as seen in your image) and select which properties you wish to define inputs for. The non-selected properties should be defaulted to the Ignore input mapping type, so that the “ignored” inputs should simply maintain their pre-existing values.
