I am migrating a field called "Group" from a dropdown field to a radio lookup field. When creating this new field ("Group1"), even though I select the field type as Radio, it is created as a Dropdown (picklist). 

Even the form definition says it is a radio field....

        Group1

        (

            displayname  =  "Group"

            type  =  radiobuttons

            values  =  data_profiler.Group[(Group.contains("Web") || Group.contains("Data"))].ID

            displayformat = [ Group ]

            sortorder  =  ascending

            searchable  =  true

        )

But it appears as a Dropdown everywhere else...

As a workaround, I figured out that if I delete the Dropdown only "searchable = true" definition, then it would display correctly.

This is a huge time waster. I hope this is isolated to my applications. If so, please advise. If this is a global bug, you'll probably want to address.
