Hi,
I have added "resolution" field to tickets in my projects as shown in the below figure,

I need to set resolution only when I Verify the ticket (Verify is the last step of the workflow). But now when I even create a ticket I am asked to fill the resolution field and it is a mandatory field in tickets. Also the drop down values of resolution contains "Done", "Won't fix", "Duplicated" and none of this value can set when I create a ticket as they are not relevant for a newly created ticket. How can I overcome this?
