I’ve a parameter quality like this:

get:
  parameters:
    - name: quality
      description: Filter by "origin.quality" by comma separated value (i.e. AA,AB,BC).
      explode: false
      in: query
      required: false
      schema:
        type: array
        items:
          type: string
          enum: [EE, AA, AB, AC, AD, BA, BB, BC, BD, CA, CB, CC, CD, DA, DB, DC, DD]

and the Swagger returns:
enter image description here

The problem is that when I select the first option, --, the GET value contains quality= (empty value) and the back-end returns an error because the quality is empty. Is there a way to remove the quality parameter from the GET when -- is selected?

Thank you.
