@paulcdd The issue goes away if you remove the default value "", which is not a valid value for your enumeration.

In #4200 (to fix #4197) we changed this so the placeholder is only shown if the default value is undefined.

@heath-freenome Would it make sense for us to change this behavior add a case to show the placeholder if the default value is the empty string AND the empty string is not included in the enumOptions?

[heath-freenome]

@nickgros @paulcdd I would suggest we add a console.error() when someone has a default value that is not in the list of options for an enum. It seems like this is a situation where the JSON Schema is incorrectly defined and the UI is doing what it was asked.
