What is the Display type in dff?

Summary:

Hello Everyone,

I have been configuring DFF and I noticed that every time I create a DFF on business object details there is another line with "_Display".

This happens when creating a DFF of type list of value and creating a value set for the field.

Does anyone know about this? what is the difference between a DFF and a dff_Display?

Please find the screenshot below as example:

Notice that a text field does not have a duplicate line with "_Display" and a list of value field with value set has it.
