D365FO – Show “NoYes” Enum field as Combobox instead of Checkbox

 I’m building a form from a table. One of its fields is a enum YesNo. I can’t figure out why every time I add it to the form it appears as a checkbox instead of a combobox.

I want a combobox with a lookup and inside display the values “Yes” and “No”.

The base enum “NoYes” is set as radio button, while “NoYesCombo” as ComboBox
