When creating new personal search ("add personal search") or editing an existing custom search, I recently noticed that the "Add Other Field" does not result in any feedback.
I can select an existing field from the "Add Other Field" dropdown, but that's it. I'm unable to select further choices for the field as the field does not get added to the list default fields above the dropdown.
For example, if I select "User / Email Address", there is no option available to filter by email address. This applies to all options in the dropdown.
There is no feedback from the system after selecting a field in the "Add Other Field" dropdown.
