Can you make a multiple choice select list have no default value?

[Christy Kennedy]

We have a custom field which is a Select List (multiple choices) that we want to make a required field. I have set the field as required in field configurations, but the system has a default value chosen from the start. Therefore, a user is not forced to select any values from the list before creating the ticket. 

Is there anyway to make sure that no values are selected by default when creating a ticket?

Solved! In order to unselect the current default value from the list, I had to hit ctrl+space (or command+space for Mac) and then click on the selected default value. It was then deselected and no default value is left

hello @Christy Kennedy ,

if there are not inconvenients, and the field is required... You can Set the default value  for this field, not informated.
